* If there was only ever one person playing, Infected wouldn't end the
game when they left

Misc
* Took /Infected Join out of it's own class... i don't know what i was
doing moving it...
* "Allow Votes" and "Use GUI for Voting" have been changed to:
<<code YAML>>
# Votes:
# # Are we going to allow players to vote for a map?
#   Allow: true
# # Should we allow players to use a GUI to choose their map
#   Use GUI: true
# # This will make a players votes worth more with the permission node
Infected.vote.<extra votes name> 
#   Extra Votes:
#     vip:2
#     staff:3<</code>>
Which will allow for a better voting system(Mulitple Votes)
