OTHER: removed PixWidget

Browse source 
PixWidget sole purpose was to paint a given pixmap. Some of PixWidgets
child classes had to create that pixmap from some other pixmaps. Thus
PixWidget introduced some kind of unnecessary double buffering.
Furthermore, those pixmaps where created even if a widget wasn't
visible. Painting directly to the widget and calling the 'update ()'
method on changes might allow Qt to do some performance optimizations.
Most likely they will be to small to be noticable though.

I also disabled the shortcuts of the titlebarmenu. They were diplayed in
the menu but didn't work. As soon as I figure out how to get them
working again I will enable them again
