Introducing icon theme support

Added some static functions to QIcon to support desktop
themes based on the freedesktop spec. It is not intended to
replace KIcon and the intention is to use it when available to
share icon cache between applications.

Applications currently using icon themes are Assistant, Designer
and the textedit demo.
