FileSystem: Allow ::openReadRaw() to break out of game directory

Browse source 
If PhysFS fails to open a path, fall back to simple FILE* handles.
Not sure yet if this is a good idea, but from observation
RMXP allows load_data() to operate on paths outside the game
directory as well, so we have to support this.
