THIS UPDATE HAS NOT BEEN TESTED!
I reviewed the code from a pull request and it looked correct.
I also took the opportunity to update some build libraries to move the plugin forward.
I will be testing this plugin for the 1.13 release.
If anyone wants to test to make sure the new options are welcome feel free!
Let me know or make a pull request on GitHub.
