Basic scripting now available for Chrome

[pmeenan]

combineSteps, sleep, exec and execAndWait are now live. I'll be adding setCookie tomorrow and then I'll probably work on packaging up the release (I will probably have to tackle click after the release but exec is kind of a hammer that you can use for anything so it might work as a work-around).

Here is a sample script:

combineSteps
navigate http://www.gogle.com
exec document.body.innerHTML='<h1>And now for the NEWS...</h1>'
sleep 5
navigate news.google.com

And the result:

I'll also start working with the different location owners to deploy Chrome to some of the other agents now that it's pretty stable (and the update mechanism is working well).
