Should allow for these features:

• Interoperability with the site's template prototype
• Interoperability with the site's template availability
• Resolving of Site and Theme as arguments to @RequestMapping methods

Interoperability with the site's template prototype requires using the site renderer so there needs to be a new TemplateViewRenderer for it. The site renderer takes a number of dependencies as constructor arguments so there should be a FactoryBean that takes care of that.

Interoperability with the site's template availability is achieved by defaulting to the default availability strategy unless one is implemented on the template using @Available.

Resolving of Site and Theme arguments needs to be added in the Blossom HandlerMethodArgumentResolver and WebArgumentResolver.
