Basic Yeoman Insight integration

See #260

I have some more questions, but I thought having some code to talk about makes it easier:

- I didn't use the `.bowerrc` since `bower-config` isn't ready yet. Is there a plan when that should happen? Should be easy enough to use bower's mechanism when it's available.
- Should the parameters be properly normalized? E.g. `jquery#2.0.3` → `jquery`.
- Should there be a way to retroactively opt-in or opt-out after via a CLI flag or is editing the config file enough?
