More Lua interface cleanup - it's simpler with cleaner underlyng APIs.
Made the sound manager mute controls readable, and got rid of system enable since it just controls system mute anyway. This was causing confusion: phantom2 was trying to use both independentlyt casuing the mute bit to be ignored. THe Lua interface changes are mostly changing methods to properties, some renames to make things clearer, and some additional properties for better control over snapshots.
