Title: Improve comment in the engine gemfile template

Improve comments, so they better describe why you should or should not declare gems in the gemspec rather that the engine's Gemfile.

I think the previous wording was ambiguous, and didn't really explain why gems should be declared in the gemspec rather than the Gemfile.
