* All of these were caused by the presence of multiple body tags on the
page, which happened because networkD3's sankey plot generates SVGs
containing body tags via SVG's foreignObject tag
* In various places, the 'body' jQuery selector string is used under the
assumption there is only one 'body' tag on the page. The presence of
multiple 'body' tags breaks reliant code in strange ways.
* The fix was to use document.body or 'body:first' instead of 'body'.
* fix appendTab for empty tabsetPanels; use spread operator to avoid having to resort to apply; upgrade grunt.
* revert back to `Math.max.apply(null, existingTabIds) + 1;` there's no browser compatibility issues there
* trigger a new `shiny:invalidated` event when an output gets invalidated, at the same time that the `recalculating` CSS class is added (fixes#1688)

* change event name from 'shiny:invalidated' to 'shiny:outputinvalidated'
* add binding and name to the new event 'shiny:outputinvalidated'
