Release version 0.1.5

• New WebDavResource class as top class of any WebDav resource
• Method to query children of a WebDavCollection
• Fix: Set the Content-Type header on PROPFIND

Release version 0.1.4

• Fall back to individual GET requests if the addressbook-multiget report failed
• Disable HTTP/2 for now, since we are getting occasional CURL errors, whose cause is not clear to me

Release version 0.1.3

• Support result truncation by server in sync-collection
• Workaround for Sabre/DAV sending invalid response elements (sabre-io/dav#1285). This caused sync-collection to fail and fall back to the slower PROPFIND based sync method.
• Do not authenticate with servers on a different domain than the Addressbook's base URI (unless redirected by the original domain)

Release version 0.1.2

• Added: SPNEGO/GSSAPI authentication (tested with Kerberos against Apache)
• Fix: During Discovery::discoverAddressbooks(), if an exception occurred, the discovery would abort. During discovery, however, exceptions are expected as several possible context paths are tried and failure is quite common. This would particularly happen when authentication failed.
