Use plain 'route'/'matchedPath' keys in the request container

The framework already exposes per-request resources under plain names
('request', 'response', 'error', 'server', 'route'), so the namespaced
sentinel constants were inconsistent. Drop them and use the same
convention. As a side effect, 'matchedPath' is now injectable into hooks
and actions like any other request resource.
