Updated the editor bar buttons for making links. Text that appear to be a URL when using the regular link button but are missing a protocol are 'upgraded' to a link-with-text so the fixed URL ('http://' + text) becomes the argument, and the originally written text is the text content. When using the link-with-text button, since the original text is only used for the URL argument it just prepends 'http://'. Otherwise it works the same as before.
