Added href logging as a config option. Log can be viewed via "investigate hrefs". If on, it logs every link clicked. It may be useful for 'debugging' and spotting malicious clients.

Anti-spam delay raised to 7 ticks. A little over half a second.

Admins can no longer be banned except by deadminning them or banning through the host's pager.
