Did some work to redo the front page with bootstrap css instead of
materialize. Generally more compatible.

The comparison that this replaced never worked and always returned false.
Changed the type(event) is Event to issubclass(type(event),Event). In
testing this shaved ~0.25 seconds off event creation.

upload new images, rework the base page and navbar to be cleaner
and more mobile-friendly.

The contenthandler was inhereting changes from previous conversions.
I made uploading betwen old <--> new events more robust.

packing the LVAlert with more information: including extra_attributes
in the superevent dict --> event dict---< lvalert. It was already
included in the httpresponse.

configure space/time_coinc_far from API, incorporate
voevent changes.

modify the superevent model so that:
 1) coinc_far --> time_coinc_far
 2) new db column: space_coinc far.

These are now available as part of the API response, but the client
code needs to be modified to edit these values in updateSuperevent.

This is going to increase the size of the LVALert
packet. But from what i've seen:

https://dcc.ligo.org/LIGO-T1800079

the network can handle the traffic. I'm going to monitor
playground once it goes live there and make a judgement
call about deciding what to include in production.

by proxy it also gets added to the LVALert. This also addresses:
https://git.ligo.org/lscsoft/gracedb/issues/184

since a user can now just query an

obj['object']['preferred_event_data']['offline']

dict entry.

I still need to add some tests, and will probably have to tweak
conditional logic, but it works so far.

django 2.2.0, django-guardian-2.2.0, new search labels, caching fixes

get_from_env() stores this value as a string, but
django settings needs it as an integer. pages fail to load
otherwise!

From what i can tell, this was never implemented. Fixes this issue:

https://git.ligo.org/lscsoft/gracedb/issues/194

if the 'is_exposed' boolean is 'True', then the superevent is
public. changing the response so that it's 'is_public' would
require more than a two-line change.

Ingests a 'FAR' field in Hz and adds it to the event data model. If
the field is present, then show it in the GRB event table on the
detail page.

This allows for persistent database connections for workers.

Adds KAGRA as a preferred idp on the shib login screen

Adding NOT_GRB and EXT_SKYMAP_READY labels in support of

emfollow/gwcelery!725

From what I can gather, there was a time when likelihood and gpstime
were integers for CWB events, and so there was an explicit casting of
them to integers. Brandon removed gpstime, but left in likelihood
before during ER6. Oops.
