Yet another project is hard to maintain, and it's mainly used for
internal use. Removing it reduces the number of options of how to get a
Oscar project running, hence making it easier.

To set a base for upcoming docs changes, the docs directory structure
has been streamlined to follow a simplified version of Django's docs.

The old _draft folder has been removed. Both files from there and the
current docs that don't fit nicely into the new structure are in _old/
for the moment.

Replaced legacy 'shop' name with 'application'

* Use `code-block` to see if that renders differently

Fix requirements_oscar.{py,txt} file extension in tutorial.

This makes it much easier to get started when contributing.  The docs
are also updated.
