Pretty much completely rewritten theme with custom HTML translator and a
few parts of the old theme extracted to their own extensions.

* Odoo installation from packages or source
* Deployment instructions for production environments
* dbfilter
Add missing support for disabling xmlrpc(/http), useful for WSGI
deployments which require running cron-only Odoo instances.
* The dashboard from the backend howto doesn't specify "name" field
which causes non-null constraint violation.
* Some useful examples uses idea.idea" model which isn't available in
8.0 so I replaced them with "note.note".
