Cleaned up code, added pod.

Fixed bug where quote_best and textquoteescape had different
ideas of what needed escaping. Added option 'encode_high' to determine
if high bit chars needed escaping or if they can be left as literals
Fixed minor bug in quote_best where it was using the last lowest instead
of the first lowest used quote char.
