Added functionality similar to GBrowse. Users can access any feature with the following URL http://<your site>/feature/<name>. Tripal will recoginze the URL, search for a feature of that name, uniquename or synonym and redirect to the page. If there are more than one feature that matches, a table with all matches will be shown and the user can select which one they want to see
