Faction Bans

Adds /f ban, /f unban, and /f banlist
Permission: factions.ban - included with factions.kithalfplayer
Also added as a /f perm that can be granted. Otherwise, defaults to faction mods.
Number of bans now shows up in f show
Banning a player will notify your faction and target player. It'll also kick the player from your faction if they are currently in it.
TODO: make /f banlist prettier
