Configtool: add --quit and --save commandline switches.

Teach configtool to save ini, board and printer files with the
--save commandline switch.  Add a feature to Printer and Board
to let us pass None for the "values" to save; this causes the
class to save the previously loaded settings instead of taking
new settings in the argument.

Also add --quit switch to tell commandline not to continue to run the
GUI.  There's not much point in running the gui after many of these
switches, but that will change in the future.  Add this --quit option
to quit early so we can begin to use this new mode for test validation.
