Shorten and improve informational content of messages, errors and
warnings.
Remove redundant info messages when they shadow an action, warning
or error message.
Improve title of "Update Footprints" to make it clear that it's
recreating footprints which have different assignments rather than
updating footprints from the library.
Don't perform the dryRun twice.
Don't use the old netlist method of loading footprints. We get
better error reporting if we do it ourselves.
Be more careful checking the last pad when checking for single-pad
nets. If the last pad has no net then pad != previouspad at the
end of the loop.

When reading netlist or updating board from schematic, if the
changes leave a zone with a net with no pads then change the
zone's net to the new net of one of it's connections.
Also improves update-board-from-schematic's dry run reporting
to include zone nets and single-pad nets.
