Blue Ridge now supports headless testing running with jQuery 1.3.2!
* updated env.js (big thanks to Chris Thatcher & Jakub Suder!)
* changed Blue Ridge to use jQuery 1.3.2 by default for both headless and in-browser tests
* removed the caveat section from the README
* (note I'm leaving jQuery 1.2.6 in the repo to give folks the ability to choose either)
