23570	Add functions to extract a URL from an arbitrary string, HTML, or the current $post	wonderboymusic		"= Scenarios

My post has a format of ""link""
- My post has format meta for URL
- OR - My post content is a URL
- OR - My post contains an <a> tag with an href
- OR - My post content is a URL followed by new line(s) and commentary

An arbitrary string might be only a URL, a URL with some commentary, or a blob of HTML that might contain an <a> with an href attribute 

Introduce `the_link()` and `get_the_link( $id = 0 )` which will arbitrarily extract a URL from a post's content.

Introduce `get_content_link( &$content, $remove = false )` to find a URL in an arbitrary string meeting the above criteria and optionally remove the found URL if it wasn't embedded in HTML content."	enhancement	closed	normal	3.6	Post Formats		normal	fixed	has-unit-tests needs-codex	lancewillett contact@… xoodrew@…
