Subject: Added basic moving using keyboard (Only works in Operation Stealth at
 the moment): - Should make it possible to complete the first arcade sequence
 legitimately Renamed input variables (Their names were mixed up between
 Future Wars and Operation Stealth): - Future Wars's inputVar1 ->
 egoMovedWithKeyboard - Future Wars's inputVar2 -> xMoveKeyb - Future Wars's
 inputVar3 -> yMoveKeyb - Operation Stealth's inputVar0 -> xMoveKeyb -
 Operation Stealth's inputVar1 -> yMoveKeyb
