task: moving main.go to cmd/app/main.go

[paganotoni]

This is related to #115. It moves the generated application main to the cmd/app folder. It ensures that newly generated apps have the main.go file in there and the refresh configuration file references it.

While working on this I wondered if we should also decouple the things we are embedding within the CLI (migrations and tasks) and move these into a separate binary we add in the cmd folder, maybe cmd/cli. I've seen some people mention that its Go style to have multiple binaries for the same codebase. But this is part of another conversation.

Changes needed to complete this task:

• Changes on the generation of a new app
• Fixer to move main.go.
• Fixer to update refresh file.
• Documentation and communication of the change.
  • https://gobuffalo.io/documentation/getting_started/directory-structure/

I added just a few small comments, that should be easily fixable.

Looks good to me! Thanks for the effort @paganotoni !

Thanks @fasmat! I don't see those comments yet. I know the Github UI for review sometimes is tricky. Can you confirm you submitted those comments? Appreciate it.

Sorry I hadn't submitted my review. 😅

It looks good to me! I tested a simple generation sequence (buffalo new, dev, build) and it worked well.
