* Returns the relative icon path for a given file extension
* Returns the relative icon path for a given file name
*
* This function should be used in conjuction with $OUTPUT->old_icon_url to produce
* a return the full path to an icon.
*
* The extension that you should pass should be just the extension, not the whole filename.
* A preceeding . is tolerated.
*
* <code>
* $extension = 'jpg';
* $icon = $OUTPUT->old_icon_url(file_extension_icon($extension));
* echo '<img src="'.$icon.'" alt="'.$extension.'" />';
* $filename = 'jpg';
* $icon = $OUTPUT->old_icon_url(file_extension_icon($filename));
* echo '<img src="'.$icon.'" alt="blah" />';
* </code>
*
* @todo When an $OUTPUT->icon method is available this function should be altered
* to conform with that.
* @todo Implement $size
*
* @param string $extension The extension of the file to get an icon for
* @param string filename The filename to get the icon for
* @param int $size The size of the icon. Not yet implemented
* @return string
