QGtkStyle refactoring

The QGtk class has been refactored into a private d class for QGtkStyle.
This allows us to re-use a lot of code for the Maemo5 style without changing
a single line in QGtkStyle itself plus we can easily add virtual functions
where the two styles need to behave different.
There shouldn't be any new functionality added (or old functionality lost) by
this commit.
