Fix type mismatches in new conf_key_info.

I suspected there'd be one or two mistakes introduced by that
transcription in spite of the test suite, and there were!

CONF_mouseautocopy had its default labelled as int rather than bool,
because it didn't _look_ boolean to my conversion scripts or to my
eyeballs - but its default value is actually a macro that expands to
'true' or 'false' (depending on platform), so it is really.

And CONF_supdup_ascii_set, conversely, is an int which had its default
labelled as bool, which was due to my conversion scripts faithfully
transcribing the same confusion in the original code.
