Fixed /essential nya (You can now hear it) :: added /essentials cleanup <days> [money] [homes] [bans] :: The cow says moo



nya: removed noteblocks, made the sound stalk you and you can now actually hear the tune.
cleanup: delete userdata of players offline for over <days> and with less money than [money], less homes than [homes] and less bans than [bans].  (all optional parameters default to 0)
moo: /essentials moo now moos

Also fixed up some formatting to be the same as the rest of the code and the user.getBanReason() method to return an empty string instead of a null when there's no ban/banreason (won't affect anything already using this method)
