First 7.x release. Code needs updating in various ways so unlikely to work out of the box. Incorporates a slightly modified form of Michael Barton's Status Messages Alter module.
Note in particular the change to the default entity table schema: any entity types using this schema definition will need a hook_update_N() to add the new column.
Changes since 7.x-1.0-alpha2:
by joachim: Added 'deleted' flag to default entity table schema.
by joachim: Fixed warnings when accessing a remote property that isn't set.
by joachim: Updated README with UI details.
by joachim: Fixed error messages when remote entities have been deleted on the remote server.
