import 30 days of intraday history on next incremental update
fixed RateLimitReached no longer being thrown by makeRestCall
added json parsing and transformation to feed to datastore
Removed unused/outdated test api
this is the actual fitbit rate limit

although we now have a more sophisticated way of respecting fitbit's rate limits by checking ad hoc response headers
fixed bodytrack time being in epoch seconds (not millis)

and allow for empty intraday records
re-enabled the limit checks

but it isn't going to used for the fitbit connector
better error handling, leverage Rate Limit headers
Merge branch 'development' into feature/fitbit-intraday
fixed default page
