* alter docstring of @api.one to mark it as deprecated for 9.0,
recommend using @api.multi instead

matching "warning" alerts
* move @api.one down the doc page to deemphasize it
* fix "backend" tutorial to remove all instances of ``@api.one``

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

things have changed since the opendays so the presentations don't reflect the
current state of affairs.
