This is required for people using apps with custom protocols. We still verify the entire URL (including protocol) against the site setting value.
Refactored wildcard_url_checker so that it always returns a boolean, rather than sometimes returning a regex match.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
