resource: Add front matter metadata to Resource

This commit expands the Resource interface with 3 new methods:

* Name
* Title
* Params

All of these can be set in the Page front matter. `Name` will get its default value from the base filename, and is the value used in the ByPrefix and GetByPrefix lookup methods.

Fixes #4244
