Kill some nonsense

See merge request KartKrew/Kart-Public!232

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

You can hear engines in 16P again, but it's not as obnoxiously loud as it was before. Additionally, I commented this function better.

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

Disable Discord Rich Presence on dedicated servers

See merge request KartKrew/Kart-Public!229

Move master server presence updates to Advertise_OnChange

See merge request KartKrew/Kart-Public!227

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

See merge request KartKrew/Kart-Public!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?

Rename the "small" variable to "isSmall"

See merge request KartKrew/Kart-Public!226

Reported by MK, apparently "small" is considered a data type for some systems. After a little bit of research, apparently it can happen when including <windows.h>... whatever, just rename the variable :p
