Log Message:
-----------
UI functions added to existing UI classes (operators adding their own menus for eg),
would stop the entire menu from drawing if they raised an exception.

now print the exception and continue.

Also added a verbose argument for bpy.utils.(un)register_module() to help test whats being registered.
