Subject: Add patch for URI decode_www_form

Plus some specs.
This should it make later possible to make Zero work with Ruby 1.8. But
at the moment it only routes to the original decode_www_form method, if
it exists. Otherwise it returns an empty Array. So this will still fail
on the 1.8 versions at the moment.
