Changes in v1.2
---------------
* Allowed menu's to have names. Submenu's can be referred to by names 
  instead of their index in the menu system. This allows user to refer 
  to submenus which are not yet part of the menusystem.
* menugen.py: Python script for converting .menu files to C source code
  See MENU_FORMAT for the format of .menu files

Changes in v1.1
---------------
* Additional handler type: Keys handler
* Menuitem handlers now have a return value of type t_handler_return.
  For all simple cases, you just return ACTION_VALID or ACTION_INVALID
  (For some types of menu items, handlers are ignored, and for 
   others the return value is ignored)
* add_menu takes an extra argument (to better control memory footprint)
  You can just set it to -1 to choose the default value
* Now the menu system support long menu's using scroll bars.
* Support for passwords and context sensitive help is added.
