Source files are no longer separated by UI and non-UI and similar,
but only by their build target.
* ui/ -> part/
* Move all source files from conf/ to part/
* Keep config skeleton definitions in conf/, needed for the mobile target too
* Move editdrawingtooldialogtest.h from conf/autotests/ to autotests/
* ui/data/icons/ -> icons/
* Move /part.cpp, /part.rc and similar files to part/
* Adapt include paths in source files
* Adapt CMakeLists.txt files (in / and in subdirectories)
* Adapt /Messages.sh
3 benefits:
* We can set the shortcut in the edit shortcuts dialog as before
* Shortcuts can be activated without showing the topbar as before
* Drawing in the toppbar is exactly as the other actions
Removed name attribute from default tools (ie those from tools.xml), so
that they now get default names, which automatically translated if the
application language is switched.
With this patch, tools.xml no longer contains strings to be translated.
NOTE: Messages.sh was not tested
