Help adding “role” support.

Hello!

I love your plugin and it is almost exactly what I am looking for. I would LOVE if it supported user roles as well. Would you be interested in putting the plugin on GitHub? I would love to help integrate that feature! I have been doing private WordPress work for about 3 years now and would love to start doing some projects in the community!

I was thinking possibly a tab for users and a tab for roles, so that the user can still restrict individual users. Also, possibly the capability to choose which has priority, user or role rules.

Let me know what you think!

Thank you,
Josh
