Jingle Sprint Release
Ringing in 2018 with convenience fixes for Tock users. For general users, pre-populated timecards that list their expected hours on each project, which will eliminate some repetitive data entry. For administrative users, filtering inactive projects out of project dropdown lists in the admin interface, and creating a department model so employees can be filtered based on where they are in TTS (18F, Acq, etc).
This release also updates the wsgi server from Waitress to Gunicorn and Gevent.
