Add ability to require logged-in user in dashboard to save or delete
Refactor _fetchWithBootstrap to process seriesList

Since _fetchWithBootstrap does a re-fetch of data, it needs to
handle an entire seriesList to do so cleanly. It now handles series
pathExpressions which return multiple series in a seriesLists

Likely other edge cases still exist but I think many less than now

Fixing TypeCast errors for time based functions.

Several functions were returning floating point startTime and endTime.

As a result, urls like the following would fail.

/render/?target=keepLastValue(sin("sin"))&from=-5minutes&format=json

The resulting error stack looks like...

Traceback (most recent call last):

    response = callback(request, *callback_args, **callback_kwargs)
