Commit Design bodies to the plate as one assembly, keeping their positions

Browse Source 
Commit to Plate now sends all visible bodies to Prepare as one object with a
part per body, so their relative placement survives. A dropdown beside the
button switches to Commit to Plate (as bodies), the previous one-object-per-body
behaviour, and the choice is remembered.
