Supporting {% url %} tag.

URLs must be registered with mango.js using mango.URLConf.register([pattern])
prior to template rendering.

register() takes the following arguments:
• URLName - the name of the URL.  Typically the last argument in a Django
URLConf.
• URLPattern - A simplified version of the Django URL pattern.
RegExp is not used to validate keywords, so the URL should take the format:
"path/<arg_1>/<arg_2>", where args are wrapped in brackets.

Once URLs are registered, the {% url %} tag will automatically match either
keyword-formatted arguments or listed arguments to the pattern and print the
rendered URL to the template.
