Some more logging added to authentication.
Fixed the display of the last simulated star.
Improve the logging when we get a 'last_simulation is after now' error.
400 errors from Google shouldn't result in 500 errors for us.
If startTime is in the future, pull it back a bit. This can happen if you do lots of simulate->save->simulate->save in a short time.
