Description
Gtk+ 3.14 introduces tons of deprecation warnings.
This series of patches removes them all.
I also took the opportunity and made all ui files valid in glade.
Although more dialogs can be cleaned up to use the cool blue buttons.
Stock buttons have been deprecated and icon names have changed.
The patches also contain the fix for Bug T3217
I also removed old Widgets like GtkVBox and GtkTable and replaced them with the new ones.
The patches can be found on my github:

They also include the fix of the gdk icon too large warnings and fix many pep8 errors.
