[HOT] a few editing questions

One thing to note is that iD automatically adds a tag called 
"imagery_used=" instead of source to the changeset.

I do not know how it determines what imagery was used, my guess is the 
background layer that was selected at the time the changes were saved.

I opened a ticket asking JOSM to return that field as well in the ctl-h 
history dialog a while back.
