Envjs envjs

I just discovered, while debugging a different test in-browser, that body.onload and window.onload are synonyms for the same event and that if you assign handlers to both, only the last-assigned one will execute. Y'all probably already knew this, and I've been a dolt, but I bring it up here because the unit tests (and therefore implementation) associated with env.js v1.1 were wrong.

I don't know if this problem got fixed in the refactor to v1.2, but I have checked and didn't find tests in the current set that verify the "synonymity" of these two event attributes. So, I'm opening this as a reminder to myself (if nobody else gets to it first :-) to add such a test and make any fixes to the code it requires.
