RR to install the Kexi app icons (*-app-kexi.png) in the proper place

[Friedrich W. H. Kossebau]

Hi Jarosław,

currently the Kexi app icons (*-app-kexi.png) are installed in the wrong 
location,
	share/apps/kexi/icons/hicolor/*/apps/
instead of
	share/icons/hicolor/*/apps

Reason is that they are in the same directory as some tool icons (kexi/pics) 
and all the icons in that directory are installed by
	kde4_install_icons(${DATA_INSTALL_DIR}/kexi/icons)
, which internally uses globs to pick up all of the icons in the dir.

Instead the app icons would need to be installed by
	kde4_install_icons( ${ICON_INSTALL_DIR} )

So okay to move all the Kexi app icons into a new dir "kexi/pics/app" and 
install from there with the proper call? (would also update the 
kde4_add_app_icon in kexi/CMakeLists.txt)? Or would you prefer another dir? 
Seems there is no standard path for that dir in Calligra (currently).

Would do that in master and 2.6, unless you go and fix it yourself :)

Cheers
Friedrich
