John Hawthorn f8f9a085cc Encapsulate "details" into TemplateDetails
When dealing with the "details" for a template: locale, format,
variant, and handler, previously we would store these in an ad-hoc way
every place we did. Often as a hash or as separate instance variables on
a class.

This PR attempts to simplify this by encapsulating known details on a
template in a new ActionView::TemplateDetails class, and requested
details in ActionView::TemplateDetails::Requested.

This allowed extracting and simplifying filtering and sorting logic from
the Resolver class as well as extracting default format logic from
UnboundTemplate.

As well as reducing complexity, in the future this should make it
possible to provide suggestions on missing template errors due to
mismatched details, and might allow improved performance.

At least for now these new classes are private (:nodoc)
