partial support for calling onload once the DOM is ready
This adds support for gecko and newer versions of opera to call onload once the DOM is ready, rather than waiting for all images in the page to load. Makes relativedate behave somewhat better. Dealing with this means jumping into the browser incompatability waters that I prefer to avoid. Full solutions for most of the major browsers are listed here: http://dean.edwards.name/weblog/2006/06/again/ However, no *license* is listed there, so I can't use that code. Also, the more involved code appears to have various issues (such as the inline IE code not working via https). So I only added the simple call to a hook needed for gecko/opera. It seems that the only standards-compliant way to do this is using the `defer` attribute to a `script` tag, using an external script that will be loaded once the DOM is ready, and can call onload. However, that has browser compatability issues of its own, since not all browsers honor `defer`. Perhaps I should really just be using one of the javascript frameworks, that include code to solve this for the major browsers. But something about them still puts me off, and this issue is minor enough that I'm willing to live with incomplete support for now.
