env.js patch -- String fixes, support for title and href/src getters that produce absolute URIs

[mikesamuel]

Below is a patch that fixes a few problems with runtests/env.js

There are a number of places where java.lang.Strings are not converted to javascript Strings.

The document.title attribute does not work.

The href attribute does not work, and the src attribute does not return an absolute URI.

cheers, mike

Attached the patch instead since the one I pasted into the ticket body was reformatted.
