Just noticed that I cannot link to a url containing an apostrophe.

I tried providing a link to Godwin's Law from Wikipedia... if I put the url bbcode in manually, it turns out like this:

Godwin's Law

Probably because it doesn't recognize that as a valid URL... and if I let the forum software parse the link (check "Automatically parse URLs"), it turns out like this:

http://en.wikipedia.org/wiki/Godwin's_Law

Minor bug, but it prevents people from referencing some sources.
