Note that authorized followup user names are hardcoded into views.py

Only submitter can upload/log to an event.
Email alerts - removed file url.  Added event summary, which currently only includes GPS time.
Fixed bug where Omega event creation failed to add EventLog entries for event.log and coinc.xml.

Zero != None.  Now taking that into account.
Yes, it's a silly edge case, but if you enter zero
as a time, you should only get events with gps times, no?

Required mod in query view as well since "slop" != "end"

Required getting data out of ligolw tables.
Incidentally added processing of Omega results.

Added info for signing up to list on home page.

Adds new dependency on pylal for gwf reading and coinc table creation.
Relies on old dependency to glue for user code which does the above.

Man there's some ugly hackage in there.
In particular, the jabber pubsub not for CBC/MBTAOnline
is cbc_mbta_online when it should be cbc_mbtaonline.

Fixed a minor type for the MBTA RSS link.
createPayload function was accidentally commented out,
which caused MBTA event creation to fail.  Yow.

New model, EventLog.
Altered event "view" view and event_detail template to show log messages.

RSS title link now points to the gracedb query page.
Maybe not right, but better than the broken link that was there.

Changed uid to graceid, since it's not a uid.
Requires database change:
    ALTER TABLE gracedb_event DROP INDEX uid
