this lifts a bunch of limits in the engine for stupid bullshit wads that
don't honor them. this should not be merged, ever. these inflate a bunch

. savegame buffer overflow: for maps that are too large; does not work
correctly, loading several times in game will eventually crash (will not
corrupt anything though)
