deploy.rb replacement for semaphore continuous deployment

deploy.rb

# The *real* deploy.rb is located in config/deploy_semaphore.rb
#
# http://semaphoreapp.com performs continuous deployment for us, so we should not perform manual deployments.
# This disables cap deploy, cap deploy:migrations and cap deploy:upload, our most frequently used tasks.
#
# On the semaphore side, use this as the deployment commands to make this work:
#
#   mv config/deploy_semaphore.rb config/deploy.rb
#   bundle install --path vendor/bundle
#   bundle exec cap -S revision=$REVISION deploy:migrations
#
# Future updates to this deploy.rb template can be found in this gist: https://gist.github.com/Narnach/6063039
