qdrupal_tmpl_path does not handle QPanel templates

qdrupal_tmpl_path does not handle QPanel templates.

A QPanel template are often named classname.class.php and the template classname.tpl.php.

It would be good to be able to use the qdrupal_tmpl_path function to get the path for the template in a nice way.

Ideas so far: 1. pass an optional argument to the qdrupal_tmpl_path function or 2. let the qdrupal_tmpl_path function detect if ".class" is in the name and act accordingly.
