Sync'ing with standalone email package 2.0.1.  This adds support for
non-us-ascii character sets in headers and bodies.  Some API changes
(with DeprecationWarnings for the old APIs).  Better RFC-compliant
implementations of base64 and quoted-printable.

Updated test cases.  Documentation updates to follow (after I finish
writing them ;).
