Massive CTF updates

I would like to point out I also plan to add some more features still, just wanted to get this merged to master for now... Additional ideas include: Better bot teamplay (automatically passing flags to players with more health than them, or more closely paying attention to team roles like defending or attacking), "timed" captures/pickups/returns (so you have to stand by a flag for ~2 seconds to pick it up, for example), and controlling which weapons (if any) a flag carrier can use (and other such abilities).

There are also a few things I may be forgetting... but yeah, that should be good.
