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

According to the new API, SRB2APPLICATION is sent instead of MODID. A contact
field was added, but there is no means of accessing it or setting it.

As a slight change, the server list will be populated even on an outdated
version of the game. (The new API was designed with this in mind.) The update
alert is still presented first of course.
