message_commonchans

Adds a umode +c so you can prevent fucktards who don't share a channel with you from messaging you privately. Simply load it and do /mode <your_nick> +c. ;3 Opers and U-Lines are exempt from this (i.e. they can always send private messages), the reason why should be obvious imo tbh fam. Additionally, since U-Lines such as NickServ are usually not present in any channels, they can always receive messages too (rip /ns identify otherwise ;]).
