Link Tool

Link creator built in jQuery that takes the current selection in the textarea to seed the "Title" field. When the user clicks "Add Link", it does, WYSIWYG-like, using Markdown.

Don't want to go full WYSIWYG as we strip everything except <p> and <a>, and clients insist on having a "link tool" not just auto-linking urls. So here it is, and it actually works.
