Fix broken PhantomJS tests, due to SSL
Fix broken PhantomJS tests, due to SSL

phantomjs defaults to using SSLv3, which has now been disabled
everywhere.  The protocol used can be changed with an option:

 --ssl-protocol=<val>                 Sets the SSL protocol
   (supported protocols: 'SSLv3' (default), 'SSLv2', 'TLSv1', 'any')

This PR makes poltergeist and the  task set this option when invoking phantomjs.
