support 8-bit content encoding? #4

I'm not super familiar with email specs, but is there any reason why this library doesn't support 8-bit content-encoding? Is it not well-supported by clients and servers?

It is not supported at the moment because RFC5322 requires messages to be US-ASCII. In addition to that, lines in a message cannot exceed 998 characters so an 8-bit part exceeding this limit has to be encoded using quoted-printable to comply with RFC5322 anyway.
That being said, I'll keep this issue open so support for 8-bit encoding is added as a configuration flag.
