[Zope] Experiment: Pyjamas with Zope

[Jim Washington]

Quick note.

I found that The "fix pyjamas" question in my previous note could be 
handled with a ~100 line python module that makes a new class descending 
from pyjamas.HTTPRequest.HTTPRequest, but overriding asyncPostImpl with 
a supported content-type, e.g., "application/json".

The module is mostly copy-paste from pyjamas.JSONService and 
pyjamas.HTTPRequest, but I'll provide it to anyone interested.  It was 
really simple to do.  Kudos to pyjamas for making fixes easy.
