Keep Contact folded until both Cockpit left panels close, and keep focus in a renamed row

Opening Utilities while Data Layers is open no longer forgets that Contact
was folded for the first, and closing one of them leaves Contact folded
while the other is still open. Enter and Esc in a drawn shape's name keep
focus in the field instead of dropping it to the page. The draw tool's
destroy test now checks it stops following the board, and the Draw gate's
amber-count comment sits on its function again.
