Fixes Issue #116: Modify rsync to return the paths synced in the patch method

Rsync now returns a list of paths that it has patched in the final step of rsync i.e. patch
```js
  if(newPaths.synced) this.synced = this.synced.concat(newPaths.synced);
  if(newPaths.failed) this.failed = this.failed.concat(newPaths.failed);
}
```
