Kari Salminen 2ca52fc007 CINE: Add support for Operation Stealth.
Add support for Operation Stealth PC 16 and 256 color versions with
AdLib and Roland MT-32 sound. Add support for 20 extended savegames
(Thumbnails, playtime etc) for both Future Wars and Operation Stealth
(20 because it fits on screen using the original save/load interface).

Details:
 - Add versioning to Future Wars and Operation Stealth savegames.
 - Add fade in effect to both Future Wars and Operation Stealth.
 - Add mouse wheel support and keyboard support to moving in menus.
 - Map middle mouse button to pressing both left and right buttons.
 - Make interface more responsive (See manageEvents() and drawFrame()).
 - Amiga versions should be completable but sound may or may not work.
 - Atari ST versions completely untested.

Game options currently supported:
 - Using original save/load interface
 - Using transparent dialog boxes in 16 color scenes (Also for PC)

Console commands currently supported:
 - labyrinthCheat (For cheating in Operation Stealth's labyrinths)
 - disableLabyrinthCheat (Disabling labyrinth cheat)
 - disableHacks (Disabling hacks, useful for testing)
 - enableHacks (Enabling hacks, useful for testing. On by default)
