Add to ContentDB

Would you consider adding this package to the ContentDB ([1])? This would make it easier to find the mod.

I'm overloaded with work and a family crisis. As soon as I can get some breathing room, I'll get back to this project, fix the open issues, and move this onto contentdb.
thank you for the suggestion.
