Added the ability to add newlines when formatting arguments

[dylanowen]

This change lets you format queries

query {
  node(my: 1, schema: 2, has: 3, a: 4, lot: 5, of: 6, arguments: 7, obj: {key1: 123, key2: 456})
}

like

query {
   node(
      my: 1,
      schema: 2,
      has: 3,
      a: 4,
      lot: 5,
      of: 6,
      arguments: 7,
      obj: {
         key1: 123,
         key2: 456
      }
   )
}

Does this play well with other tools? Or are they dynamic depending on the length of the line?

[dylanowen]

Unfortunately it's not dynamic, but you can enable it via the style struct.
