* 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'.
The date inputs used css classes like icon-arrow-right, which no longer works
with font-awesome 4.x. This change uses glyphicon arrows instead, which are
included with Bootstrap and therefore don't need a separate HTML dependency.
