------
* Completely rewrote the Manifest parser code. Now is much simpler and less bug-prone.
* Also completely re-write Manifests tests to be 1/3 the linecount, with the same coverage.
* Because of the large change listed above, there may be some regressions. Please report these as you see them.
* Upgraded SQLAlchemy to 0.8.2, upgraded some other libraries to the latest versions.
* Completely reworked how the config works. Now there are three configs: `secrets`, `config` and `machine`
* Renamed `GiottoProgram` to just `Program`, also renamed `ProgramManifest` to just `Manifest`.
* Got rid of any mention of jinja from settings, also force all templates into 'views' folder.
* Removed sqlalchemy and added in Django ORM to replace it. This is a backwards incompatable change.
