Added some hidden divs to indexGraph.jsp that are shown if javascript detects that SVG is not supported by current browser.  This allows user to click on links to open the descriptions.
Also made a couple of the fixes made directly on server(revert back to jquery 1.9 from 1.10, remove the deprecated browser.msie from jquery.tooltip
Corrected a minor bug in the indexGraph.js where the lines were not hidden when the desc div was and also fixed the resizing of the svg to being too large.
