A HttpModule that moves ViewState to the bottom

I came across this via LarkWare News - it's a HttpModule that moves the ViewState data in the HTML down to the bottom of the page.

The idea of doing this is that the browser then gets to render all the regular page content before it hits the ViewState blob.

Looking at the comments, there appear to be a few small problems, but it could be a useful thing to use on ViewState-heavy pages once it is more robust.
