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
Better plan:

```js
var syncedPaths = {
  synced: [],
  failed: []
};

...

syncedPaths.synced.push('/some/path/that/worked');
...
syncedPaths.failed.push('/some/path/that/failed');
```
