fix missing jQuery.browser in popupforms.js to work with jQuery 1.9
to attach an event handler, use "on" instead of the deprecated "live" (depends on jq 1.7)
don't attach these event handler on document to prevent the event from bubbling up the whole DOM, which can lead to poor performance

Revert "don't attach these event handler on document to prevent the event from bubbling up the whole DOM, which can lead to poor performance"

This reverts commit 9a037a23e9affaff9a6fc2ea0166dbcfd55ea402.
