chore(build): add source map support (#654)

* chore(build): add source map support

this creates two new files:

```
//# sourceMappingURL=algoliasearch.helper.js.map
//# sourceMappingURL=dist/algoliasearch.helper.min.js.map
```

- add exorcist for having the source map via browserify (otherwise only inline)
- add appropriate options for uglifyJS

Further nothing is changed. This setup is compatible with `source-map-explorer`

IFW-622

* chore(build): more readable commands

* pin

* Update scripts/build.sh
