groundwork for window port interface change to add_menu

groundwork only - window port interface change

This changes the last parameter for add_menu() from a boolean
to an unsigned int, to allow additional itemflags in future
beyond just the "preselected" that the original boolean offered.

There shouldn't be any functionality changes with this groundwork-only
change, and if there are it is unintentional and should be reported.
