DDF-903 - Removed the es5 option from the jshint to expose es3 (older browser) warnings/errors

-Removed the es5 option from the jshint configuration.  This will expose IE8/IE9 issues like trailing commas.
-Once I turned off es5, other errors cropped up so I fixed those where I could.
DDF-903 - added x-ua-compatible to index.html file.

-This will prevent IE from loading in quirks mode and load in the latest install IE document mode.  Quirks mode is very inconsistent.
