Moved Janrain API key into a separate file (and changed to a new key)
Added feedback-type option to local comments.
Fix for scroll errors in JS console (what is the intented effect?)
Merge branch 'local-comments' into argus-history-integration
Cleanup of diagnostic markup. Added Login/Logout links.
Visual cleanup of argus view. Limited its height and added scrollbar.

Responsive scrolling in argus now reflects its (apparent) purpose, which
is to maintain a consistent position for its controls when the viewport
is scrolling.
