Add support for other gamemodes (Ultiduo/Ultitrio/Passtime)

[Ooglely]

Just have to add the list of maps/configs

can't assign myself yet, but I'm working on both ultiduo && ultitrio. This seems like an issue where I can just read the code base and follow along with your current style so this will allow me to familiarize myself with work done.

Passtime support was added in #34
