Use non-minified main script

Bower [recommends](https://github.com/bower/bower/issues/393) not to use minified files for your main scripts (leave it up to build tools to minify if desired).

```
The primary acting files necessary to use your package. While Bower does not directly use these files, they are listed with the commands bower list map and bower list --sources, so they can be used by build tools. Do not include minified files. Files should not be versioned (Bad: package.1.1.0.js; Good: package.js).
