[1v1] Challenge

[Magikarp]

Swo-Z might be a bit difficult but when you use the !challenge command it comes up with a list of people (like store would come up with options) and you pick who you wish to challenge.
That person would then get a prompt in chat (if this popped up as store people could abuse it to fuck with people trying to switch weapons) asking them if they would like to !accept or !deny the request.

If !accept 'ed both players would be moved to the bottom arena and points would be disabled for those 2 (if possible to remove point farming).
Who ever won would then move up an arena like usual and points would be turned on for them again.
