Entities with states

History grid

If the specification does not say otherwise then every entity should have a history grid in its details form:

If the specification says that we should use the extended history grid then we should use this one.

It has the additional option to pass the reson of a state change.

If the specification does not say otherwise then every entity with a state should be copy-able.

But when we copy it we should always set the copies status to draft.
