Title: Add chart support for powerpoint slide

The following part is a bit tricky:
- Currently, I wrote temporary excel files for embedding. Should use embedding document, but not enough time to do that. So I used msexcel-build instead.
- Not yet to customize the chart's style. But I can keep working on this feature.
