Added oc:tags and oc:favorites in PROPFIND response. It is possible to update them with PROPPATCH. These properties are optional which means they need to be requested explicitly

/**

* Class OC_Connector_Sabre_Server
|
|
*
|
|
* This class reimplements some methods from @see \Sabre\DAV\Server.
|
|
*
|
|
* Basically we add handling of depth: infinity.
|
|
*
|
|
* The right way to handle this would have been to submit a patch to the upstream project
|
|
* and grab the corresponding version one merged.
|
|
*
|
|
* Due to time constrains and the limitations where we don't want to upgrade 3rdparty code in
|
|
* this stage of the release cycle we did choose this approach.
|
|
*
|
|
* For ownCloud 7 we will upgrade SabreDAV and submit the patch - if needed.
