• Added: Plugin to automatically map GET requests to non-files to PROPFIND
  (Sabre_DAV_Browser_MapGetToPropFind). This should allow easier debugging of
  complicated WebDAV setups.
• Added: Sabre_DAV_Property_Href class. For future use.
• Added: Ability to choose to use auth-int, auth or both for HTTP Digest
  authentication. (Issue 11)
• Changed: Made more methods in Sabre_DAV_Server public.
• Fixed: TemporaryFileFilter plugin now intercepts HTTP LOCK requests to
  non-existent files. (Issue 12)
• Added: Central list of defined xml namespace prefixes. This can reduce
  Bandwidth and legibility for xml bodies with user-defined namespaces.
• Added: now a PEAR-compatible package again, thanks to Michael Gauthier
• Changed: moved default copy and move logic from ObjectTree to Tree class
