Fix skinning issues with panels on index.html and add better responsive CSS
Merge branch 'bootstrap3' of https://github.com/sakaiproject/3akai-ux into issue-3548
Tweak style of panels on index page
This commit adds an `anon` class to the html tag when an anonymous user
visits a page. This allows elements to be appropriately hidden through
CSS alone.

The following things have been removed/cleaned up:
 * The `oae-anon-toggle` class for hiding the lhnav toggle
 * JS code related to hiding comment functionality
 * Trimpath code related to hiding comment functionality
 * A reference to the unused class `topnavigation-logged-out`
