Upgraded Closure Library to add support for IE9
Upgraded Closure Library to add support for IE9

The parts of Google Closure Library included so far were dated from a version
nearly one year old, using browser detection to trigger specific behaviors for
IE, no longer relevant in IE9. Exceptions have been put in place in this
updated version, but the fix still relies on browser detection, and a new
upgrade will be require to support future versions of IE.
