Also updated the VOEvent such that IVORNs include an incrementing

references to earlier VOEvents.

log message creation time.

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 serialized objects to LVAlert messages. This required to move the serializers themselves from api.py to view_utils.py. Some light refactoring ensued.

Changes to allow MBTA events to be submitted via coinc.xml files. Submitting by .gwf files now gives a deprecation warning.

Fixed event creation logic (in API only) for backwards compatibility with old client. The new function fix_old_creation_request will take a request object from the old client (which has analysisType), guess at the pipeline and search, and then insert those into the request object.
