Subject: Changeset: 61 [BUGGED] Move object kind enums to use generated
 ToString and FromStrong

The old mechanism rely on a specific prefix to Ires and GameObject string representations, but the generator currently leaves the enum value. Therefore all editor (e.g. drag & drop) and IO (e.g. ires loading) mechanisms are broken.
