Issue #1803408 by robertom | daniela basualdo: Fixed Content Creation with Relate Fields: Undefined index: entity_id() in _relation_select_field_widget_form().
Fix code formatting from last commit.
Issue #1860892 by manicato: Fixed Submit problem when having several Relation Select widgets.
This is about as good as it gets for now. All things should work as before, with interface a little different. File uploads still don't work.
Best working situation: fields except images work; endpoints search/select works; Instances are apparently handled correctly.
OK, this doesn't work, but I learned some shit about how this all goes together -- apparently the field system doesn't loop through for each field instance, so we do our own little jig?? WTF? Committing, so I can go back to square 1 on 7.x-1.x.
Issue #1856266: Fixed Field titles display entity instead of relation id.
