Disabling auto-generate on db:migrate

[ciembor]

Hello, I can't find such option in a README nor documentation. I think it would be useful. Did I miss something and it's already possible, or does it need a pull request (if confirmed it's a good idea).

I think auto generation gets executed via rake task, installed this way:
https://github.com/voormedia/rails-erd#auto-generation

So you can probably remove file lib/tasks/auto_generate_diagram.rake and it should stop auto generation on db:migrate

Thanks :).
