Adds simple clans.
Chat format now is playername: message when there is not clan With DeClan, chat format is: [clan] playername: message
/clan or /c join <clanname> = Join <clanname>, creates if <clanname> does not exist leave = Leave your current clan sethome = Set your clan's spawn, only if you are the leader home = warp to home promote = make someone else leader. Only works if you are already leader chat or c = a private chat with everyone in your clan. help = displays all commands and what they do.
NOTE: /clan sethome and /clan home can be disabled from the config.yml
Default group is all.
config.yml is used for persistence, do not edit things unless you want them to change in game.
