Merge branch 'chris/menuclass'

This replaces the old popupmenu.class-based context menus with Intuition-based ones.  This provides the following advantages:
- No more RMBTrap, so menu shortcuts work without having to be manually handled
- Standard menus now display when not over a contextual zone, so the not-really-contextual menu items have been removed
- No buggy system crash problems, so they are always enabled now
- Menus can be attached directly to gadgets, so the history menu is now attached directly to the back/forward buttons (however they now need to be periodically refreshed as they can't be created on demand)

Additionally, the menu items now have images.
popupmenu.class is now only used (optionally) for form select menus.  This code has been bug-fixed and is now toggleable from the prefs GUI.  However, due to the inability to display more items than fit on the screen, it still isn't recommended to use it.
