Further simplifying making operators with menus;
now you can add an 'invoke' callback:
WM_menu_invoke
which will automatically generate a menu with choices and assign
it to the property 'type'.
What also helps typing is the new RNA_enum_is_equal() function.
Here's a paste of the now committed 'clear parent'. Note the
undo push will become a flag too.

(Brecht; fixed small bug in RNA_enum_is_equal!)
To evaluate: solving dependencies for multipe scenes... probably
will make a more generic flush call.
