UP-4011, UP-4012: Adding respondr theme skin and gallery as hidden to the -lo.templates

https://issues.jasig.org/browse/UP-4011
https://issues.jasig.org/browse/UP-4012

Adding respondr theme skin and gallery as hidden to the -lo.templates to allow the proper display in DLM fragment administration.  Adjusted the gallery code in xsl to only be present if the user is authenticated(otherwise the gallery isn't present).  In fragment administration there was a bug where $ was not mapped to up.jQuery causing the page to not work properly which has been adjusted.

This addresses the gallery not being present while administering a fragment as well(UP-4012)
