Allow plotting of multiple board layers per plot in Python.

Since the always plot the edge cuts layer  option was deprecate,
the ability to plot multiple board layers was exposed through the
PLOT_CONTROLLER object.

Added the interactive plot information which was overlooked during
version 7 development.
