Reviewers

This adds some useful utility functions to WebAPIResource for getting
the item resource or list resource, given a set of keyword arguments for
URL resolution.

It also provides a function that now handles the actual building of the
URL. This can be overridden by projects if they have additional work
needed for URL resolution, or have a custom resolver.

Djblets and Review Board unit tests pass.
