include object in result buffer if it exists...

don't repr the return value, the dict containing it will do that for
me...

don't go into subchildren and update them to pull in there children
just to find out the childCount...  DIDLLite now doesn't include it
if there aren't any...  (This may need to be tested w/ the Intel
software, but works great w/ the D-Link DSM-520)...  It makes
browsing shoutcast genres doable now..
