Dynamics.js Uncaught TypeError for arguments.callee in strict mode.

[djfrsn]

Hello Michael,

I've run into an issue using Dynamics.js in React component's with strict mode and ES6 classes. Using methods such as spring which use arguments.callee.defaults throw TypeErrors's. To solve this, I change the arguments.callee to the following format(dynamics.methodName.defaults) in order to avoid errors in my project. Is this something you would be interested in changing or having a pull request for?

Error Message:
Uncaught TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them

Example Solution for 'spring' method:
applyDefaults(options, arguments.callee.defaults);
now
applyDefaults(options, dynamics.spring.defaults);

A pull request would be awesome! Would love better ES6 support!
