stack to check for this and avoid unexpected tool starts
When a user clicks on the "Add Component", "Add Power" or "Add Footprint"
icon, they want to add the item. Requiring an extra click on the screen
before selecting the component/footprint is not needed.
Also remove an implicit zone merge that was happening when the user
edited the zone parameters. This appears to have been a feature but it
happened without a) telling the user and b) having the option to prevent
it.

One way to do this would have been to keep the Uuids in the editor
copy. However, this opens us up to errors if we forget a Save As or
export path and end up writing the Uuids out somewhere else.
In the end, it felt safer to store a map of the original Uuids and
restore them if we happen to save the editor footprint back to the
board.
