(bug 45002) made EntityId data values work with the new jQuery.valueview.

IMPORTANT DEPENDENCY: ValueView extension's I09cd9f42ca1a22f11ff102a18e56321b451eed34

There is one bigger todo left, which would be to make get/setRawValue of the EntityIdInput
expert more consistent; both should take and give the same kind of values.
This will be done in a follow-up though, the situation has not really become worse since
before this change-set.

- patch set 3: Entity ID input now auto resizes.
