Update Events / Gestures modules with event.js 1.1.3

##Summary
Updated event.js to 1.1.3. This event.js is a custom build, I have a pull request out currently (https://github.com/mudcube/Event.js/pull/4). This is my first pull request against fabric.js so not sure the policy on updating libs.

1. Added wheel, shake, drag and orientationChange. Wheel is included with events module, other included with gestures. Not sure the exact mixin architecture, I can change my implementation as needed.

2. Fix possible bug in the .dispose method (resize handler only removed if isTouchSupported == false, static_canvas.class.js, line 991).
