Added IRC Permissions (you can configure them in ircPermissions.yml)
.players has the Permission command.players (which is enabled by default)
.mute <player> can mute Players from IRC (needs command.mute IRC Permission)
.unmute <player> unmute Players from IRC (needs command.unmute IRC Permission)
.message <player> Sets the PM Session to the Player (needs command.message IRC Permission)

To let a Player PM with a IRC nickname he needs cloudchat.pm.irc. The Syntax is /m <ingame prefix from irc.yml> <nickname> <message>
