add jquery source map file

Since jQuery 1.9 , [JavaScript Source Maps](http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/) is supported.

File `zp-core/js/jquery.js` has this line:
```
//@ sourceMappingURL=jquery-1.10.0.min.map
```

This cause a **404 error** on loading the source map file in Chrome.

You could either choose accept this pull to add the source map file (I think might be a good choose for dev branch) or just delete the line from JQuery file.

Thanks.
