KFileItemListView notifies KFileItemModelRolesUpdater of changes of the
visible index range and the icon size with a delay, to prevent that
expensive operations are triggered repeatedly, and that scrolling feels
sluggish because the GUI thread is blocked by icon loading.
This patch ensures that the "long" delay of 300 ms is only used when
the zoom level is changed, and the "short" delay if only the visible
index range has changed.
Thanks to Christoph Feck for helping to analyze this problem!

Take the style option vertical/horizontal margin into account

Thanks to Frank for pointing out two other problems with "Page Up/Down" and providing
a better way to fix these problems. :)

When sorting by, e.g., "Size", and the name is used as a fallback
because there are multiple files with the same size, the refreshItems
signal that is received when a file's name is changed either with the
dialog or outside the current view did not cause the view to be resorted
after commit d70a481180. This patch fixes
it.

The most recent commit from the KDE/4.11 branch (new unit test) had to
be modified slightly due to the changed signal emission when resorting
the model changes only the groups, and not the order of the items
(groupsChaged instead of itemsMoved).
The idea is that we no longer assume that the "expandedParentsCount"
for each item will be stored in the QHash. It is only accessed for
items which are expanded, and which are not top-level items (i.e.,
which have an expandedParentsCount > 1).
Some unit tests are added to improve the coverage of the affected code.

Currently, KStandardItemListWidgetInformant::itemSizeHint() calls the
model's data(int) method for every single item, but the full data is
actually only needed for the size calculation in Compact View. In
Details View, no data is needed at all to determine the size required
for the item, and in Icons View, only the name is needed.
This patch makes it possible for subclasses of
KStandardItemListWidgetInformant to provide an alternative way to
obtain the "text", and implements this in the subclass
KFileItemListWidgetInformant.
The final goal is to achieve that the QHash which contains all data
for a file item is only created if it is really needed, e.g., because
the view needs access to the data for displaying the item on the
screen.

Removed all signal-slot-connections related to DolphinNewFileMenu->errorMessage(QString)
in DolphinMainWindow and DolphinContextMenu and replaced it by a better solution.
Now we make use of the already existing DolphinNewFileMenuObserver singleton class to achieve a better
error handling, because every newly created DolphinContextMenu instance registers himself by DolphinNewFileMenuObserver
and we use this to connect the errorMessage(QString) signal of every DolphinContextMenu instance to the errorMessage(QString)
signal of the DolphinNewFileMenuObserver singleton class.
So we need only one connection from DolphinNewFileMenuObserver to DolphinMainWindow (or to DolphinPart) to
collect all error messages thrown by every DolphinNewFileMenu instance.

When the name of a file is too long to be shown inside the maximum
number of lines, the last line is elided. However, there were several
problems before this commit:
(a) "lastTextLine", which contains the text to be elided, was not
assigned the complete remaining text, but only the part that would
be put into the last line if there were more lines following. This
may be less than what would fit into the line because we try to not
break the text at random points.
(b) QFontMetrics::elidedText() was not given the width that is available
for the last line (that would be maxWidth), but only the width that
would be occupied by the text if there were more lines following
(line.naturalTextWidth()).
(c) The variable "nameWidth", which is required to calculate the QRectF
that is reserved for the name, was not updated correctly.
The result is that the text was sometimes trucated too early (especially
if there would be a line break early in the text if we had more lines
available), that there may be insufficient space to show the "...", and
that the hover/selection rectangle might be too narrow.

KFileItem::determineMimeType() not only determines the mime type, but
also the icon. For folders, it looks for a .directory file inside the
folder, where a custom icon might be stored. This can take quite a bit
of time and cause the problem that some folder's type still appears to
be "unknown" when the view is shown.
We can work around this problem by caching the folder mime type in a
static QString and applying to to all folders, which can be identified
easily with KFileItem::isDir(),

This patch changes the status bar text dolphin shows when a folder is
hovered. It now shows full folder info, eg:
"mydir (folder, symlink to /opt/mydir")
instead of:
"mydir"
This is consistent with dolphin's behavior on regular files, and
DolphinPart already does that (DolphinPart::slotRequestItemInfo has no
special cases for folders).

The purpose of this change is to give the user a chance to see hover
file information if it doesn't fit in the status bar, by allowing to
click on the file and hover on the status bar.
As it's now possible to have status bar texts starting with "<qt>",
DolphinPart::updateStatusBar() must escape strings. Otherwise,
filenames such as "<qt>Tes<font color=red>t" would be rendered as HTML
data in konqueror's status bar when selected.

KFileItemModel::setData() should not only cause a resorting when the
sort role is changed. The name is always used as a fallback if the sort
role of multiple files is equal, therefore, renaming a file can change
the correct order of the files even if the files are not sorted by
"name".
Unit test included.

Storing values which are equivalent to default-constructed QVariants
does not make much sense because QHash::value returns the same value
even if the corresponding key is not found in the hash.
This commit reduces Dolphin's memory consumption in large folders by
up to 7.3% (tested a folder with 100,000 files in Details View) and
reduces the time required for loading a folder.

The problem was that we drawed the overlays using KIconLoader, which can
be very slow, every time an item appeared on the screen. This commit
makes sure that not only the icon, but the icon including overlays is
cached in QPixmapCache. Therefore, the overlay drawing is done just once
for each icon+overlays combination.
For previews, the overlay drawing is done in KFileItemModelRolesUpdater
just after the preview is received.

The problem was that items are removed from m_visibleGroups while
a QMutableHashIterator iterates over this hash, such that the iterator
can become invalid. The solution is to use a QHashIterator instead,
which takes a copy of the hash. Therefore, it is not affected if
m_visibleGroups is modified in any way.
