Move enums for max SI and EXI devices to their respective .h file, and rename them.
Use only those enums in BootManager.cpp. Same thing in Movie.cpp
Change one instance of MAX_BBMOTES to MAX_WIIMOTES in Movie.cpp, since movies do not support balance board.
Some settings that bootmanger reads from game ini can be changed while a game is running, so we don't have to revert these back to what they were when starting the game, unless they were actually changed by the game ini.
Fix signed/unsigned warnings that pauldacheez pointed out.
