Title: Break secondary beams - new pull request

Works like this:

```javascript
beam.setSecondaryBeamBreakIndices([1, 3]); // renders groups of two in a 6 note beam
```
Also, it looks like I accidentally committed the secondary bream break test in the grace note branch. But it's been updated now to work with this new implementation.
