RSS feed improvements:
- send 404 when feed id missing/unknown - added a guid element for each feed item (make the difference between 2 different 0/1 items - they have the same link element) - don't update last_check unless some news are available - new images/updated albums removed from the 0/1 feed item - added 5 different feed items for new images/updated albums (generated by grouping post date) with more information, thumbnails and links git-svn-id: http://piwigo.org/svn/trunk@1549 68402e56-0260-453c-a942-63ccdbb3a9ee
