Deal with non-module URIs

[nrabinowitz]

Per Sebastian's test page in #17, we probably need to support URIs without a specific module, if they include specific markup in the a tag. I think potential markup here should include:

• class="awld-type-*"
• class="awld-resource"

Suggested approach:

• Revise the registry to use module paths as keys and values that can be strings, regex, or functions to test a single link
• Revise the code that looks for module links to cycle through all links and test each (I don't think this will be significantly slower - still O(m*n))
• Add a "default" module at the end of the registry with tests for the above markup - all the module needs is a title and noFetch
