added failing test for nested params in .route_params
Add failing spec to demonstrate conflict with 'prefix' and 'version'
Fix: header-based versioning with use of prefix.
Related to #133: the value of env[PATH_INFO] is no longer altered with path versioning. Got rid of the prefixer middleware, which is not generic across versioning schemes, but specific to the path versioner.
Merged with upstream.
Fix #280: grouped parameters manged in route_params hash.
Fix #304: present x, :with => Entity returns class references with format :json.
Fix #196: root requests don't work with prefix.
A spec for #182 for a catch-all.
Fix: Ruby 1.8.7.
Fix #174: the value of PATH_INFO is no longer modified during request.
Removed note on mounting with a path, which doesn't work.
Fixed yard documentation generation.
