fix mojibake reversion in display of utf8

Browse source 
When displaying a ByteString like "💕", safeOutput operates on
individual bytes like "\240\159\146\149" and isControl '\146' = True,
so it got truncated to just "\240".

So, only treat the low control characters, and DEL, as control
characters.

Also split Utility.Terminal out of Utility.SafeOutput. The latter needs
win32, but Utility.SafeOutput is used by Control.Exception, which is
used by Setup.
