Cross-probing: clicking empty area in schematic highlights pads with no net on PCB

Bug Description

When using cross-probe highlight (highlight tool selected in both eeschema and pcbnew), clicking empty area in eeschema will send a $NET: "" cross-probe message to pcbnew, which will then highlight any pads on the board that have no net (because the footprint has pads that are not linked up to symbol pins).

This probably isn't quite the right behavior. We should probably add a "clear highlight" message, and send that instead when clicking in empty space.

Hi Jon,
I agree, We should add a "clear highlight" message.

I recently had a similar issue in Eeschema, and added a specific message
$CLEAR: "HIGHLIGHTED"
in eeschema/cross-probing.cpp

(using message $NET: "" was not a very good idea)
