Fix segfault on shutdown

There was a problem deep within how the menus were connected and when and
what gets deleted. It was clearly related to a menu which was kind of
global. In order to better understand the code flow I eliminated the
ExtraMenu code: it was used only to get the Remember-Menu into the
Window-Menu. Instead of having a singleton of the Remember-Menu and fight
against the shaky interconnections we just create a new one on demand
and delete when the menu gets deleted. Looks like this fixes the problem.

The menu code needs more love anyway.

Closes #1118
