Add `object-curly-newline` rule

http://eslint.org/docs/rules/object-curly-newline

'object-curly-newline': [2, {multiline: true, minProperties: 1}],

The above will enforce putting the contents of objects (everything inside the braces) on a newline unless there’s only one property.

The main issues with this rule is that it then enforces that all objects with one property is inline {foo: true}. I think it would make more sense not to enforce anything then, as having it inline or not when only property depends on the situation.

The second issue is that it also applies to object destructuring, where having multiple properties inline is quite ok. const {foo, bar} = unicorn();.

No, I meant, it should have fixed it to:

Object.assign(stream, {
	isTTY: true,
	columns,
	rows
});
