[kde-gtk-config] Implement changing cursor theme for GTK applications
Review Request #126704 - Created Jan. 10, 2016 and submitted
Implement changing cursor theme for GTK applications. It's needed to set cursor theme for Firefox and other applications that use GTK configs to set cursors.
Tested on my local machine. Seems to do what it should properly.
All in all it looks quite good.
I'd suggest creating a CursorThemesModel inheriting IconThemesModel that overrides some methods (you can add virtuals). Otherwise we're adding weirdly specific logic.
Also I'd say it would be really good to be able to show some preview of the theme somehow, otherwise it's hard to tell them apart.
