v0.5

Supports Rails 7

Support Rails 6

This release updates the gemspec to allow use with Rails 6. No code changes are included.

Rails 5.2 support

• remove lib/generators to have less code to maintain
• remove dependency on rails and replace it with dependency on activerecord since that's the only part this gem should care about
• remove acceptable_attributes method and depend on using strong parameters when creating these models
• remove rails4? and in_rails_3? methods since they're no longer necessary
• added rubocop file to make sure I didn't make any dumb mistakes
• added Dockerfile and docker-compose.yml for easy building
