Implement GM_xmlhttpRequest

Committed in r10886.

[skrulx, 2009-02-21 23:22:07]

The implementation of GM_xmlHttpRequest :)

This patch also includes a fix to GM_addStyle so it actually works, plus a small
spelling correction in V8UnitTest.

Oh and note that something got a little screwy at the end of
greasemonkey_api_test.js and v8_unit_test, so you'll see a lot of removed
duplicate lines in those files.

You can add the style element to document.documentElement, which is always
defined and seems to work great in my experimentation.

Maybe call this var 'textNode' ?

Do you want to always append the new style node as a child to documentElement or
only when there is no head?
