JSON support rolled into Exyus

[mca]

I posted an update to the exyus runtime this afternoon. I also updated
the tasklist demo app on the live site (http://exyus.com/xcs/
tasklist/) to include support for updating data to the server using
XML, ATOM, or JSON. You can check out the tasklist.js file for
details.

Check out the associated transform documents (at the sample app page)
for details on how to send and recieve JSON using exyus.

I'll proly concentrate on bringing up support for JONS and other
features to the SQL-backed store over the next week.
