and was originally motivated by problems with the presentation of the EMBB.
At a basic level, the page obtains information about the Event log messages
and EMBB logs via AJAX calls to the server. This information is fed into
dgrid tables. Extensive use is made of the 'put-selector' to create DOM
elements. This approach eliminates the need for JavaScript code and django
template loops that build HTML. As not all of the features are correct in
Linux browsers (Konqueror, Iceweasel) more work needs to be done.

Added context processor for login URL, added login URL to base template, added embedded discovery service page.

There are two base templates here.  One with logos on top, one
with them in the footer.  Need to decide which to use befmore pushing live.

Ditched drop-shadows in top menu bar.  (ugly!)

Added info for signing up to list on home page.
