doctor: better quick option propogation for stats
* use contextmanager for quick stats instead of editing global state
directly
* send quick to lots of stat related functions, so they
could possibly be used without doctor, if someone wanted to
* if a stats function has a 'quick' kwarg, send the value
there as well
* add an option to sort locations in my.time.tz.via_location
- restructure query code for cli, some test fixes
- initial query_range implementation
refactored functions in query some more
to allow re-use in range_range, select()
pretty much just calls out to a bunch
of handlers now
