fix missing jQuery.browser in popupforms.js to work with jQuery 1.9
Declare minimum plone.app.jquery dependency (1.7.2) in setup.py.
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
We need the event handler to be attached to document, as forms may loaded via
ajax. So:
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.
