Overview
Comment:Add initial usage of the User Pointer

Still need a way to get to the third menu and also need to actually do
something with the User Pointer function.

Baby steps though.

Test using the User Pointer to change another menu

Requires the Window and Menu variables to be global(?) in scope. I.e.
move outside of main routine.

Interesting thing about the refreshing of the other menu... check-in: 328662366f user: atomicules@lavabit.com tags: origin/master, trunk
