popovers in a modal stay on screen when the modal is closed

Created by: demike

To reproduce this issue just open the modal on the examples page, click on the button inside and close the dialog

@fat: Not attaching the tooltip / popover to the body solves the issue in bootstrap-tooltip.js just use insertAfter(this.$element) instead of appendTo ... + use tip.offset(tp) instead of css(tp) for positioning
