* Creates the server menu screen (s).
|
||||
* Handles the keypresses for this screen.
|
||||
* Creates the server menu screen(s) and creates the menus that should be
|
||||
* displayed on this screen.
|
||||
* It also handles its keypresses and converts them to menu tokens for
|
||||
* easier processing.
|
||||
*
|
||||
* NOTE: menuscreens.c does not know whether a menuitem is displayed INSIDE
|
||||
* a menu or on a separate SCREEN, for flexibility.
