Removes skeleton dev mode for zf-development-mode

- This is a better solution, as the development mode functionality has a lot of
  general-purpose application, vs. being hidden in the skeleton.
Merge branch 'feature/zf-development-mode'

Use zf-development-mode instead of hiding the development mode console
routing/tooling in the Application module.
Remove console config from Application module

- as it's no longer relevant
