Hook node indexation to changes tracking. We should probably have a parent indexation core plugin, extended by lucene, change tracker, and elasticsearch.
Make sure to exclude recycle_bin from indexation for synchro
Remove dependency of authfront.session_login to gui.ajax - we use protocol detection anyway.
Add an optional stream=true parameter to the changes request. Json data is return one per line, the result is not real json but it can be that way easily "streamed" by consuming clients.
Filehasher: publish rsync extension support through a plugin exposed parameter - document sdk methods for rest access.
Fix event sent when appending data to an existing file (must be an update instead of a create)
Merge remote-tracking branch 'origin/develop' into develop
