Use module loader rather than using the Angular bundles

[pablodenadai]

We should be resolving and packaging dependencies with a module loader. Bundle files aren't included in the distribution packages since rc-0.

Would be easy with webpack, but if you want to keep actual systemjsbuilding system, have a look on this seed : ;)

@phiphou for some reason webpack never grew on me. Perhaps it's the config file that I find a bit messy.

Surely there's a way of getting it to work nicely with Gulp. Well, I'd think so.
