Added ability for Haxfred to log links

Posts to http://haxfred.hax10m.com
Haxfred ignores some links

Links to gists or haxfred.hax10m.com are now ignored by Haxfred
Added listener to automatically change Haxfred's name

If 2 Haxfred’s get loaded on (or someone else is using the name
Haxfred) and Haxfred turns into Haxfred1 or Haxfred_, then this
listener changes the config.nick to Haxfred’s current nickname, that
way he’ll still respond when spoken to.
Merge remote-tracking branch 'haxiom/haxfred-(dev)' into clonez
