[FEATURE] Add option for a Rails only API app.

[esbanarango]

Hello and thank you for this project. It's great and has saved me a lot of time on common and repeated configurations.

One configuration I think is missing and it's very important and common nowadays is having the option for a Rails only API app.

Some suggestions (ideas) for this configuration would be to:

• Delete:
  • option - Template engine
  • option - Front-end framework
  • option - Install page-view analytics
  • option - Use a form builder gem
  • option - Install a starter app
• Add:
  • option - API templating
  • Rabl
  • Jbuilder
  • act_as_api
  • option - API engine
  • Grape
  • Rails-API
  • option - API documentation
  • Swagger
  • Apipie

There could be more options for a deeper configuration but those are the ones that I come up right now.

Thank you again for this project.
