The old code would watch the free space on a mount point, i.e.,
determine the free space again, in 10-second intervals, only until the
view became invisible once (even if it was invisible only for a very
short moment, i.e., while splitting the view).
This commit ensures that the mount point is watched again as soon as
the corresponding view becomes visible again.
Moreover, the object that watches the free space for a mount point is
shared among all views that show URLs that belong to this mount point.
To achieve this, there is a central cache which can be used to obtain
an existing MountPointObserver for a certain path. If necessary, a new
MountPointObserver is created and added to the cache.
The MountPointObserver is removed from the cache and destroyed only if
no views use it any more, and no new users appear until the next update
(which happens every 10 seconds). This prevents that the free space is
measured repeatedly when changing the current directory on the same
mount point.
Many thanks to Emmanuel Pescosta for the initial ideas to factor out
the "free space" code and to establish a central storage for the
"observer" objects, and for providing many good suggestions how to
improve the code!

This does not work properly yet, there are probably quite a few bad signal/
slot connections due to KUrl -> QUrl. However dolphin starts without
crashing.
Accessibility is not ported since that changed quite a lot from Qt4 -> Qt5
and I have no idea how it is supposed to be used.

Since Dolphin 2.0, we have stored the selected items in a QSet<int>,
which is neither space-efficient nor particularly fast when inserting
many items which are in a consecutive range.
This commit replaces the QSet<int> by a new class "KItemSet", which
stores the items in a sorted list of ranges. For each range, we only
store the first index and the length of the range, so we need a lot
less memory for most common selection patterns, and we also save quite
a few CPU cycles in many situations, because adding an item to the
KItemSet will in many cases not need a memory allocation at all, and
it's particularly easy when inserting sorted items into the KItemSet in
a row.
KItemSet contains a minimal subset of QSet's API which makes it
suitable as a drop-in replacement for our needs. It also has iterators,
such that the items can be iterated through easily, also with foreach.
One advantage of KItemSet compared to QSet<int> is that the items are
always iterated through in ascending order.

This prevents that the GUI freezes if there are many files inside the
directory, or if the access to the directory is slow for some other
reason.

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.

- Updated both the Dolphin KPart and context menu to use the new
DolphinRemoveAction class to manage "Delete/Move to Trash" actions.

To change the icon size in the Places Panel to, e.g., 60 pixels, add
the following lines to $KDEHOME/share/config/dolphinrc :
[PlacesPanel]
IconSize=60
A value of -1 means that the standard "Small" size should be used
(which has been the default before this commit).
It is planned to add an "Icon Size" submenu to the context menu of the
Places Panel in KDE 4.10, but we cannot do this in the 4.9 branch
because of the string freeze.

Follow the suggestion from Vishesh Handa and copy the ResourceWatcher
code from kde-runtime instead of creating a dependency. This will of
course get removed again as soon as Nepomuk's resource watcher will
get a public API.
Related changes:
- Animate changed items for the details-view in case it is not expandable
- Remove the hardcoded "isHidden"-code in KStandardItemListWidget and
allow derived widgets to define themselves what means "hidden" within
their context.
The current code needs a lot of bugfixing, but lets make this in smaller
steps during the next days...
The places-entries for searching revealed some serious issues in
combination with the search-panel. Move the filtering away from
QDockWidget and bring it back below the search-bar.
Up to now the view-engine only provided a model-implementation that
supports file-items. The view-engine always had been designed to be able
to work with any kind of model, so now a KStandardItemModel is available.
The plan is to convert the places panel to the new view-engine. It should
be no problem to fix this until the feature freeze - in the worst case
the places-panel code could be reverted while still keeping the
KStandardItemModel changes.
