Re-organized into two submodules: service and uploader.

Moved all the existing service code into the `service` submodule.

Stubbed out project and GUI frame for the uploader. Idea is to have a GUI that
infers all the correct meta-data from media tag values and creates service,
songs, and performance records appropriately based on the tagged mp3/ogg files
of the performances.
