Qt: Update display filter bookmarks when list changed

Recreate the display filter bookmarks menu only when the list
has changed, not every time the display filter changes.

The list changes when removing an entry from the menu and
when changing the list in the "Manage Display Filters" dialog.

Save the list when removing an entry from the menu.
