CinE sprite overlay rewrite
|Reported by:||SF/next_ghost||Owned by:||sev-|
I've rewritten CinE overlay list to use Common::List, implemented some missing pieces of Operation Stealth overlay code (they don't work properly yet but it's better than nothing) and split script.cpp into script_fw.cpp and script_os.cpp. Rename script.cpp to script_fw.cpp before applying this patch. xref.txt changes are in the patch.
