[ALOY-861] When creating a new controller, add arguments statement to the JS file

When creating a new controller, it would be great if Alloy inserted the following line automatically into the JS file:

var args = arguments[0] || {};

It would save me typing it every time.

Create a new alloy app

Run alloy generate controller mycontroller

Ensure that the generated controller has as its first line the following:
var args = arguments[0] || {};
