#167310 - KarenS appropriately points out that pre_render is not gone - maybe this changed during the development?

#156638 - fix #submit handler that was broken when upgrading to 6.x, the #submit handler changes were accidentally backported

don't use hook_init - this was inefficient (init'd on every page) and prevents code from running with aggressive caching installed, refactoring this code actually made it simpler too!

create branch 'DRUPAL-5'.
