Add play command feature for existing gamemodes

[deyoyk]

/play

lgtm
should also add things like /sb /skywars /bedwars. Simmilar to whats on the network now

I need to think this one through a bit more, currently having all this logic in one command seems a little slop

Perhaps an enum with every single different type of "game" including things like SOLO_BEDWARS and perhaps aliases? Would also probably need some sort of Boolean on whether it would warp party automatically and such.

I'm not too sure how to add this without just a bunch of commands with each game mode, but maybe swofty can find a way to fit it into an enum implementation.

Not gonna merge just yet, probably wait till the replay refactor comes in and we'll decide a better way to do it with a game registry that's more widely used
