Require space before/after arrow function's arrow (arrow-spacing)

Browse Source 
Enable [arrow-spacing](http://eslint.org/docs/rules/arrow-spacing.html) rule, code with space before/after arrow function's arrow is easier to read.
```js
() => {};
(a) => {};
a => a;
() => {'\n'};
()=> {};     /*error Missing space before =>*/
() =>{};     /*error Missing space after =>*/
(a)=> {};    /*error Missing space before =>*/
(a) =>{};    /*error Missing space after =>*/
a =>a;       /*error Missing space after =>*/
a=> a;       /*error Missing space before =>*/
()=> {'\n'}; /*error Missing space before =>*/
() =>{'\n'}; /*error Missing space after =>*/
```
