Bug 573697 - [GTK3] MenuBar leaks native memory

This change ensures the GTK+ accelerator group allocated by Decorations
is released upon destruction.

In addition, the accelerator group is removed from menu items, upon
Decorations.destroyAccelGroup() (and prior to recreating it during
Decorations.fixAccelGroup()). This prevents a crash in GTK+ code, due to
trying to use the now released handle.

Manual snippets are also added to the set of GTK bug snippets, for
future manual validation.
