Let 'display action' routine set menu->cursel (ie default menu item).
Remove 'opt' parameter I added to action routine (not that useful).
Make man page slightly closer to reality.
- pass 'menudesc' and 'arg' values to post_act() and exit_act()
- add set_menu_numopt() for variable length menus
- fix (badly broken) allocation/free of dynamic menus
- option to allow default selection to be the exit line
Correct calculation of menu height and whether scrolling needs (was wrong
if a height was specified that was smaller that the number of lines needed).
Move keypad(m->mw, TRUE) to stop core dump when newwin() fails.
Allow for calling code hacking m->h (to reduce number of lines displayed).
Add a MC_NOCLEAR option to leave menu text showing when doing action.
