lint:fix script not present in app package.json

[knownasilya]

ember-cli expects a lint:fix script which it uses when running blueprint generators, like ember g helper test. It returns this message:

WARNING: Lint fix skipped: "lint:fix" not found in package.json scripts. New files might not pass linting.

we may want to stub it to do nothing, else we'll want it to run lint from the root level vs from within the app/addon.

That said I feel it's likely we replace the default ember blueprints with engage versions, should speed up the process not having all the ember cruft in the blueprint timeline making scaffolding nicer all around, and that way we can match output to the conventions of the pod setup that apps are configured for (pods for route templates/files/controllers only, classic/co-location everything else)

I like that.
