98.0 Performance

[jK]

After some profiling

I've pinpointed the main cycles hog to be the lua mutexes, but apprently the worker threads don't run any lua, so is there a need for these mutexes at the moment?

Their removal results in significant performance improvement, and from some tests I haven't seen any desyncs (even in games between a version with mutexes and one without).

Even if they're needed and I've missed something, they can probably be heavily optimised.

Thanks!

(look at the CritSection sheet)

I've profiled both the dev version and the dev version with locking commented out.
There's a noticeable improvement, but it's still significantly slower (Gameframe event is nearly twice as long) than having no locks.

EDIT: forgot to mention, data was averaged over 4 games each.
