Return appropriate titles for links that don't lead to html content

When exploring a link, if it returns a content type that isn't text/html return the content type instead of a title.

I implemented something similar in my code using curl_getinfo($this->var, CURLINFO_CONTENT_TYPE); Then if it's text/html I get the title... and if it's something like PDF or MP3 I can return something like PDF document or Audio File.
