New /away system implemented, changes nick to Nick[Away] while away.
Updated NickServ 'RegExclude' to include optional [Away] or other status in nicks.
Added OVERRIDE command to transfer identity to a stale connection.
New nick handling code, uses alphanumeric portion to store on disk and use internally, but allows for all IRC nick characters to be used.
Support for new OVERRIDE command.
Misc fixes.
