Change in server intialization

The most noticeable change in this release is the reworking of how the service is initialized and started. Initialization is now a separate step from starting the server. This is to facilitate running the service within other WSGI engines. See README for details.

Also notable is @b2m's addition of a preview service to display the entire contents of a given row when hovering over it. This is opt-in. See README for details.
