added an option to comment the code, i.e. --type comment

I needed to just comment the code and not delete it, so I did a small modification and added an option to the task,typing --type comment will comment out all the code.
I did this because then the commented code is removed when minified in production.
I don't know if it's a feature that you'd like to have on the plugin, but I needed it so I added and I thought you might want to look at it :)
