version 0.9 - new difference converter

complete rewrite of the difference converter system that uses
deepops.deepdiff() to work out differences more simply, based on the
configuration dictionaries directly

rule system replaced by simpler 'excludes' list which matches keys in
the configuration dictionaries: -x/-X/-y replace old options

add various debugging options: -P, -C, -D, -V

added -O option to suppress output
