FS #5535 - Chopper game ported from IPL by Ben Basha. This commit is chopper_with_menu_api.diff with some changes by me: fixed the bug with the unmatching calls to menu_init() and menu_quit() (causing freezes after game #6); added keymappings for the sansa, gigabeat, Ondio and Archos Recorders; and changes to work with mono LCDs. This should now run on all targets with bitmapped LCDs.

+/* - attempt to make the tunnels get narrower as the game goes on*/
+/* - make the chopper look better, maybe a picture, and scale according to screen size*/
+/* - use textures for the color screens for background and terrain, eg stars on background*/
+/* - allow choice of different levels [later: different screen themes]*/
+/* - better high score handling, improved screen etc. */
