CinE Script system
First version of script system replacement.
This patch includes savegame hack from patch 1870447 and globalVars arithmetic for Operation Stealth. It depends on SharedPtr template from patch 1895703.
New code includes Doxygen descriptions. I've tested this patch by playing Future Wars through the office and swamp to the village and saving and restoring games a few times, it seems to be working correctly. This is the smallest possible change that actually does something.
