Fix for WCM-822.

Ignoring javascript urls rather than reporting them as broken.

 Consider:
      <a href="javascript: document.getElementById('platformGenreForm').submit();">Not a broken link!</a>

 Links like this will still be counted, but now no attempt will be made to 
 verify their validity  (just like mailto, ftp, etc.).   Trying to validate
 links like this would mean forcing the validator to embed a javascript
 engine & execute arbitrary javascript code.  That's not a good idea,
 so the lesser evil is to punt.
