Var and func def modificators.

covert int Math.some() => 123;

to

Object.defineProperty(Math, "some", {
    value: function some() {
        return 123;
    },
    writable: true
});
Dotal getters and setters definition is done.

covert int get Math.rand() => 123;
		covert int set Math.rand(int val) => console.log(val);

		to

		_ColaRuntime$$updateProperty(Math, "rand", {
    		get: function rand() {
        		return 123;
        	},
        	configurable: true
    	});

    	_ColaRuntime$$updateProperty(Math, "rand", {
        	set: function rand() {
          		var val = arguments[0] !== undefined ? arguments[0] :
_ColaRuntime$$error("Argument `val` is required!");
        		return console.log(val);
    		},
    		configurable: true
		});
Some fixes. Class translation spec is done.
