Updates for IRC. Adds-in private messaging.

Just a basic implementation of private messaging. Works alright. On irc format looks like /privmsg botname :playername message to send a new message to player player. To respond to a message synatx is /privmsg botname :%r message.

Update /r for irc private messaging.

More IRC updates.

Some extra error messages.

Because this is annoying me.

And because I don't think it will break any configuration files.

For the sake of conformity.
Merge branch 'patch-5' of https://github.com/RlonRyan/RR_ForgeEssentialsMain into patch-5
