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

Version 1 implemented -- has cleaner error handline.

Added a 404.html template.
gracedb/view raises Http404 when event is not found.
Event.getByGraceId should now never return None.

On failures, users will get nicer looking messages and admins will get email.

REQUIRES db schema mods in upgrade-3-4.sql

Changed display of all date/time data to be UTC.
GPS times display UTC times when cursor hovers over them.

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.
