Issue:
spaceBetweenParents isn't multi-line friendly
This fails:

```less
.button-base(
  @baseBackgroundColour,
  @focusBackgroundColor: @baseBackgroundColour,
  @hoverBackgroundColour: lighten(@baseBackgroundColour, @buttonBackgroundDelta),
  @activeBackgroundColour: darken(@baseBackgroundColour, @buttonBackgroundDelta)
) {
  // ...
}
```

Pull request description:
fixes #130: spaceBetweenParens fails with mulitiline definitions
just stripping the newline characters from raws for now. we can get fancier if we decide to implement something more intelligent. this should cover most cases in the meantime.
