Remember originating box - for default to save back to

[e3krisztian]

Work with multiple boxes, having the same bead, but potentially with different input-maps (or other future volatile meta).

[ ] develop requires box name, saves it in workspace's meta
[ ] save saves to box from which it was originated (unless it was a new or developed from file)
[ ] update updates to another version only in the originating box, must be forced to load beads from other boxes
