[Zope] update on my XML-RPC woes

[I-Min Mau]

OK, some good news:
  I was able to locate more tips from :  "XML-RPC with ZClasses"
http://www.zope.org/Members/teyc/pipermailXMLRPCWodes/

  So I have implemented the one major change:
1.  Fix the import error to support "encode string"-by adding
      from base64 import encodestring
    and I went back and re-adjusted that block to the way Amos had it

because per my earlier email, I had already fixed the subclassing error.

But it still isn't working yet!
