Hey, this hack will allow for ?blog=urlname as well as ?blog=shortname instead of just ?blog=id

Heres the hack for the v1.8.x releases of b2evo.

Add [ File - /blogs/inc/MODEL/collections/_blogcache.class.php ; Line - 183 ]

	function & get_by_shortname( $req_shortname, $halt_on_error = true )

			return $r;

		$Blog = new Blog( $row );
		$this->add( $Blog );

		return $Blog;
