drop non functional gtk cursor theme
Since we're using Xserver's builtin cursor font, the whole code reacting Gtk cursors theme signals isn't doing anything useful at all - it just recreates the cursors from the same source they originally came from and readjust them for all clients, practically doesn't change anything.
IOW: we haven't any cursor theming in xfwm at all, just many Loc that don't do anything useful.
If we'll actually implement that feature, it should be quite different in several places:
- directly use XSETTINGS spec instead of proprietary Gtkisms
- carefully consider extending the spec to to also store the actual cursors (instead of just the theme name - since remote client don't necessarily have the same themes)
- do it in ScreenInfo instead of DisplayInfo - since xsettings operates on root window, thus on Xscreen instead of Xdisplay.
