curses memory: 'anything identifier'

Three or four instances of one simple memory leak.  Allocating a union
'anything' to pass to add_menu(), then not doing anything with it.  The
value gets copied so there's no reason for the original to stick around.

[There are still lots of other memory leaks.]
