Trying to get up to speed with Zinc 2.4.3 before moving to 2.5

I have been tampering with this Zinc port of and on for months now. I prefer to send in a pull request so someone else can get a head start on this.

Not all tests are working and, please, check what I did with conversion of ByteArrays, Strings, QuadByteString etc... because that is where the pain was in getting this code running.
