Log additional headlights event when render asset for doc set up with crema,
and when render asset for doc *not* set up with crema.
This will allow us to more directly compare crema vs non-crema use of generator.
Fixed a bit of lint
Check that document isn't undefined.
Remove extraneous check against undefined, and fix the bad whitespace that previous change introduced.
Log just one "rendered with crema" or "rendered without crema" event per day, rather
than one per PS session, since the user might keep PS running for several days, and we
really want to see if they're using it often.
Clean up some lint and remove an unneeded test.
Added another event to make calculations easier with generator vs crema events.
