Made changes to store permission info on the Event objects themselves. This speeds up some searches by an order of magnitude with respect to guardian's get_objects_for_user.

Removed SimpleSearchFormWithSubclasses. The only thing that needed this was the gstlalcbc report page, and there is a simple workaround instead: just get a list of Event objects, and upcast them to CoincInspiralEvents. One wrinkle is that the matplotlib call 'fill_between' (which had given us that nice grey region on either side of the expected IFAR line) seems to hang now. I emailed Chad and commented this out.

Changed views to assign default permissions for Event as well as Event sublcass instances. Also added call to get_objects_for_user to filter the queryset returned by search.

Changed migration for existing event permissions to apply defaults to *both* the Event and the event subclass instances.

Added storage_engine=MYISAM so that the new guardian tables will be created with the same database engine as the others.

Removed permissions from Event class meta. This is unnecessary, as syncdb and south will not pick it up. Only works for new models.

Added view permission for event, created permission objects for existing events, and added code to apply default permissions when new events are created.

Added guardian to installed apps and added ANONYMOUS_USER_ID=-1 and GUARDIAN_RENDER_403=True to settings.

Fixed bug due to Django 1.6 update. The get_or_create call in refresh_users_from_ldap.py needed some default arguments. Otherwise, it tries to create a user with an empty username, and that will collide with another user with an empty filename and cause an unhandled exception.

Removed settings/update.py and modified branson.py to reflect updates. No changes required for settings/default.py

Fixed URL sent out in event creation LVAlert to a valid URL, namely the URL of the event file in the web interface.
