break_chained_methods behaviour

There shoud be option to set max num of chained methods before breaking it:

Eg:

```
"break_chained_methods": 2

this.$("#fileName").val().addClass("disabled")
.prop("disabled", true)
```

I see no sense in breaking when there is only 1 meth (it's not a chain in this case :)). So maybe default behaviour should be: if there is more than 1 chained meth then perform breaking.

Start by locating the existing break_chained_methods option and the formatter tests that cover chained calls. Check how the current setting decides when to break, then define the threshold behavior shown in the issue and verify the example output plus the default behavior in tests.
