toaster: add toaster code to bitbake

This patch adds the Toaster component to Bitbake.

Toaster is a module designed to record the progress of a
Bitbake build, and data about the resultant artifacts.

It contains a web-based interface and a REST API allowing
post-facto inspection of the build process and artifacts.

Features present in this build:
* toaster start script
* relational data model
* Django boilerplate code
* the REST API
* the Simple UI web interface

This patch has all the development history squashed together.
