New Features

timeseries.Gammatone filter and sounds.Gammatone filtered noise classes!
Thank you scipy team for making this simple!

Minor Improvements

579ef1a - En route to implementing universal calibrations, load and save them in a specified place for each hardware object instead of the horrific olde way which was built into prefs for some reason
prefs attempts to make directories if they don't exist
plenty of new debugging flags!

a775723 - Sleep before graduating tasks, lateral fix until we rework the task initiation ritual
360062d - pad sounds with silence or continuous sounds if they aren't a full period length
6614c80 - Revert to old way of making chunks to make it work with both padded and unpadded sounds
Import sounds module directly instead of referring from the package root in tests
Terminal node pings pilots instead of an erroneous reference to a nonexistent Terminal.send method
47dd4c2 - Fix pinging by passing pilot id, and handle pressing start/stop button when subject not selected
Fixed some GUI exceptions from trying to make blank lines in reassign window, improperly handling the Subject class.
