Make chrome.appWindow.create() provide access to the child window at a predictable time.

When you first create a window with chrome.appWindow.create(), it won't have
loaded any resources. So, at create time, you are guaranteed that:

	child_window.location.href == 'about:blank'
	child_window.document.documentElement.outerHTML ==
			'<html><head></head><body></body></html>'

This is in line with the behaviour of window.open().
