tag latest working 0.7x

@bhaskarvk 
I can not add tags on a  to your repo.  could you run these commands in the lastest master?

```bash
git tag -a "leaflet_js_0.7.x" f8685528710ff1bcacbc199b030a9752b7daff35 -m 'End of support for leaflet.js `0.7.x`. Beginning of support for leaflet.js `1.x`'
git push origin --tags
```
