classes who can build their Apprise URL based on the one provided

The intent of this is to make Apprise a little more userfriendly

to people who aren't familiar with constructing URLs and wish to

use the ones that were just provied by their notification serivice

that they're using.

This function will return None if the passed in URL can't be matched

as belonging to the notification service. Otherwise this function

should return the same set of results that parse_url() does.
