Respect breaksWith option

@jakubpawlowicz: I make this to track the line endings issue which is noticeable on Windows.

The above line doesn't take into account the breaksWith option.

@jakubpawlowicz: this is the offending line https://github.com/jakubpawlowicz/clean-css-cli/blob/master/index.js#L263

I tried checking for options.format.breakWith but that didn't work.

console.log(options.format); // breakWith=lf
console.log(options.format.breakWith); // undefined
