Static properties combining ::, =>, and number literals break syntax highlighting

[appsforartists]

Using transform-function-bind and transform-class-properties together makes syntax highlighting very fragile. For instance, this won't highlight:

export class Example {
  _someStream = someOtherStream::map(
    thing => 1
  );

  constructor() {
    console.log('this should be highlighted');
  }
}

but replacing the 1 with an identifier will highlight correctly.

Just added a test to catch this in the rewrite. See "re-rewrite babel-sublime" #293.
