Move "empty" and "not empty" PrimitiveConditions to direct containments

[GoogleCodeExporter]

What new or enhanced feature are you proposing?
In r2282, PrimitiveConditions "empty" and "not empty" were created for
VisibleThings, but these are contained within 'conditions' and not
explicitly through direct containments. 

These should be moved to direct containments 'empty : Condition' and
'notEmpty : Condition', just like DomainIterator's PrimitiveConditions.

What goal would this enhancement help you achieve?
Cleaner metamodel; more consistent; and more likely to pick up errors.
