This one follows the domain rules, it matches things that start with http://, https://, //, or none of those. It also will allow up to 127 levels of domain/subdomain/subsubdomain/etc, which is what is allowed. each section can only be up to 63 characters, contain only letters, numbers, or hyphens, but can't start with a hyphen. It will work with all tlds and country level tlds, including ones that don't exist yet. It matches tlds that are only letters, infinite length, if it has a country level one then that one has to be two characters. it can have a trailing slash or not, if it does it will include everything after that slash, I still need to update it so the url can't end with a comma.

It skips urls that are contained in quotes, so it won't mistakenly turn the urls that are hrefs or srcs into links.
