Port the Gtk platform theme to Gtk+ 3

The major changes compared to the Gtk+ 2 version are:

 * Everything is ported to modern Gtk/Gdk API.
 * GtkFontChooserDialog is used instead of deprecated GtkFontSelectionDialog.
 * Hiding buttons on dialogs (like OK/Cancel) is no longer supported, as it is
   impossible to do that with dialogs using GtkHeaderBars.
 * Some workarounds were added to the QGtk3Theme constructor to correctly work
   with Gtk+ 3.

[ChangeLog][Platform Specific Changes] The Gtk+ platform theme has been ported
to Gtk+ 3.
