Kill some nonsense

See merge request !232

Fix engine sounds' dampening to a sane value, now that the bug preventing it from working properly was fixed.

It caused problems with crash reports not being made if the current working directory gets changed. Not even recommended anymore per the drmingw readme

Move master server presence updates to Advertise_OnChange

See merge request !227

Make "divide by zero" or "modulo by zero" errors show the file and line of where it happened

See merge request !228

Shouldn't break scripts as it stops execution as soon it happens, like it already does.

This will probably call DRPC_UpdatePresence slightly less?

See merge request !226
