add KSP-AVC version file for auto-module checking

Dearest NathanKell et al,

I just started working with @tyrope on a project to add a version checker to KSP modules. I know that it would help me a lot! He said that helping him contact module authors would be really helpful so here I am! If you would be willing to accept this patch we would really appreciate it!

The KSP Addon Version Checker is my attempt at trying to have some sort of version checking available for people who play KSP with lots of mods. more information and source available [right here on github](https://github.com/tyrope/KSP-addon-version-checker)

**Note**: You're heading up so many projects! Thank you so much!! I hadn't quite realized until listing out my favorite mods and their authors and your name kept coming up. :) When I have more time I'd like to get PRs for all your mods, but I'm trying to do one per author to gather feedback and just get the word out a little bit.
