Static object expressions on prototype

[dhruvdutt]

Currently, we have support for transforming static Methods on prototype from

Controller.staticMethod = function(param) {
	var bar = "webpack-cli";
};

to

static staticMethod(param) {
	var bar = "webpack-cli";
}

But, we don't have support for transforming object expressions like this:

Controller.optionsObject = {
  bar: "webpack-cli"
};

We need to transform it into:

static optionsObject = {
  bar: "webpack-cli"
};
