function boxes_footer in Boxes 6

Same name and namespace in other branches

1. 7 boxes.module \boxes_footer()

Implementation of hook_footer().

All ajax requests are targeted back to the current page so that the proper environment can be re-setup. Here in hook_footer we then detect that this is an ajax submission and handle it.
