Preparing the code to support 'order_by()' chaining after '.all()' and '.filter()' in mixins.
Add '.destroy()' to the GraphMixin and the Neo4j backend
Not sure why the code was like it was. I enabled support again for reflexive but directed relationships, even when implies a reduntant formset when the schema have them.
Commiting for perform a merge with "upstream"
Merging with the commits of "Destroy Neo4jDB" and "Reflexive relationships bug fix"
Added autocomplete for "Collaborators" datatype
Ref trello#343. For reflexive relationshps, show only as target those nodes are not itself
Commit for merge master branch
Now the "media_files" are stored in a folder with the "id" inside the "graph_slug_name"
Fixed the bug that save the reflexive incoming rels as outgoing rels
Fixed the desapiring relationship forms in the node_editcreate view
