Album desc. not returned in Gallery Remote API

[witchi]

Hi,

The Gallery 2 Remote API defines that the 'fetch-albums-prune' command can return additional album information as indicated in the 'extrafields' field. In the current implementation the 'extrafields' response contains "Summary" and "Description". However only the "Summary" field actually has a value returned in the response ("album.summary"), the "Description" doesn't. This can be fixed very easily by adding
"$response->setProperty('album.description.'.$i,$album->getDescription());"
in the foreach loop of the fetchAlbums function in GalleryRemote.inc. It will require a new return field however (e.g. "album.description") so it may require a version change of the protocol.

If this is not feasible then at least the fields in "extrafields" should be adapted to indicate that only the "Summary" is returned as extra information.
