function editableviews_style_helper::query in Editable Views 7

Add anything to the query that we might need to.

For the base and each relationship that brings an entity table, add the entity ID field for that entity. This ensures that we can load the entities when we need to get form elements for them.

We do this for all relationships, not just those which have editable fields on them, because we may need access to entities that editable field entities need to point to when creating entities.
