[PATCH v2 4/6] patman: Make most bool arguments BooleanOptionalAction

[Douglas Anderson]

For boolean arguments it's convenient to be able to specify both the
argument and its opposite on the command line. This is especially
convenient because you can change the default via the settings file
and being able express the opposite can be the only way to override
things.

Luckily python handles this well--we just need to specify things with
BooleanOptionalAction. We'll do that for all options except
"full-help" (where it feels silly). This uglifies the help text a
little bit but does give maximum flexibility.
