Add ability for commenters to enter a URL without a protocol

When posting a comment on the a page with this module applied, there is
an optional input for the commenter to give their URL,presumably their
website. However this input currently validates (via JavaScript) to
allow URLs only iff they have a protocol.

Common use cases when someone is asked for their website in my
experience is to then receive a URL without a protocol, confounded in
that most web browsers will accept this form and automatically add the
http protocol, where a webserver may then redirect to https by default.
This means that all the magic happens behind the scenes and most folks
don't particularly care to think about protocols when entering web
addresses.

Yest this input will only validate true and allow comment submission if
they do.

So now it will allow a protocol-less entry into the URL box.
