Added my Stack class to the base lua script.
Split off the Audio, Game and Map Lua functions into separate files to make luastate.c more manageable.
Further splitting up of the Lua related code. ls_bmp.c for the bitmap objects, ls_gfx.c for general graphics, ls_input.c for input devices, ls_gamedb.c for the game database functions.
