Added a preliminary saving routine for Operation Stealth (Disabled by default, needs more work still. WIP!).

Added backgrounds' name saving (8 names in Operation Stealth instead of just 1 like in Future Wars).
Added 256 color palette saving and restoring (One of the palettes isn't properly handled yet though).
