Overview of changes from libgdata 0.6.3 to libgdata 0.6.4
=========================================================
Major changes:
* Fixed the behaviour of gdata_entry_get_id() for GDataPicasaWebAlbum and GDataPicasaWebFile, which was previously *broken*
Use gdata_picasaweb_album_get_id() and gdata_picasaweb_file_get_id() for the equivalent results now
* Don't send ETags if a query is modified since it was last used; this improves libgdata's behaviour for programs which re-use GDataQuery instances
* Lots of documentation fixes and improvements
* Added missing #includes to gdata.h
* Improved error reporting about network and proxy problems
API changes:
* Added GDataPicasaWebAlbum:album-id, gdata_picasaweb_album_get_id(), GDataPicasaWebFile:file-id and gdata_picasaweb_file_get_id()
* Fix the value returned by gdata_entry_get_id() for GDataPicasaWebAlbum and GDataPicasaWebFile; it is now a full URI
