Minify aem.js ?

Not completely convinced this is a good idea but... We should not write `aem.js` from https://github.com/adobe/aem-boilerplate/ since this is a generated file from this repo. How do we avoid people making PR against that file in the boilerplate, apart from writing it in the doc... Minifying the file would solve that problem (they would need to find the source) but on the other hand, this will block people from easily look at the file.
For sure, #20 is a must-have prior doing this one.

Review the generated aem.js file and issue #20 first, then determine how this repository produces the file referenced from the AEM boilerplate. Define whether minification is the accepted way to discourage edits to the generated file; done means the agreed generation process produces a minified aem.js without preventing source inspection.
