GSoC update: It runs!

[kpreid]

I completed enough of the E-on-JavaScript improvements, and wrote the beginnings of one Data-E kit in Cajita, together with the Updoc tests for it, and a Makefile to cajole the JavaScript and "animate" the Updoc - convert it into a HTML page that actually runs the tests.

I also improved various readme files and pages, hopefully such that someone else can get it all installed on their own system starting from my project page without too much prior knowledge.

Near-term plan: Put aside the EoJS, and get the Data-E kits working; then the surgeon; then the CapTPConnection; then define, document and implement a CapTP-over-HTTP protocol.
