Refine your search - no way to reselect 'everything'

The way the 'refine your search' box is on the frontpage of beta.d.o, if you choose one, you can't go back to the original 'everything' setting, which is bad U.I. The only option is to refresh the page, which is a big no no. Solution is simple, add a radio button chosen by default with the value 'everything' and replace the "Refine your search" to just "Search".
