relation 7.x-1.0-alpha2

• New README.txt
• Some Views support
• As relation endpoints have been moved to field storage, this should work with mongodb (if the mongodb_field_storage module from the mongodb project is enabled) but it's untested yet.
• Relation entities were fieldable but the relation edit page didn't yet work. This is now fixed. You can get to the relation page just after creation (if using the dropzone block). Also, if you enable the dummy field module and attach a relation field to an entity then you can see the relation attached to the entity it belongs to. click on the header of the field to get to the relation entity page. There you can see the edit tab. I will create a video of this.

Rules support, documentation and more tests are needed for a beta release.

API changes: what was $relation->entity_keys is now $relation->endpoints[LANGUAGE_NONE] and the results of relation_query are no longer loaded, you need to take care of that. Also many proprietary relation_query methods have been removed in favor of EntityFieldQuery which the query class now extends.
