Mismatched anonymous define() module

[harryxue1999]

When Hammer.js is used with AMD (RequireJS), in some cases the hammerjs module is not properly defined due to lack of String ID.

Current implementation: define(function () { return Hammer; });

Suggested implementation: define('hammerjs', [], function () { return Hammer; });

This problem causes require('hammerjs') to fail, causing some important functions (particularly with jQuery) to be undefined.

you could

var Hammer = require(['hammerjs']);

I'll look into it though.
