Add thor-os

[opensourcecollaborationnow]

Hi jubalh :)

So, I would like to release this operating system: thor-os

Note: I updated README.md with thor-os, thor-os is simple operating system in C++, written from scratch. reference: https://github.com/wichtounet/thor-os

As promised, one more operating system on the list :D

thank you for accepting my pull request, this is really cool :)

A few things:

• Make your commit subjects look like: Add thor-os instead of updated readme with... Since this project only contains a readme this makes more sense.
• Let's omit filling worlds like 'simple', 'small' etc since probably too many projects would claim this.
• Don't repeat the name of the os after you listed it.

So in this case I would just write * [thor-os](https://github.com/wichtounet/thor-os) - Written in C++ from scratch.

And if you want to add multiple OSes you can create multiple commits but one pull request containing those commits is enough.

Thanks for the feedback. If possible, could you check the change I made?

I await your reply.

Yes, but now you made two commits. Please squash them together next time. git rebase -i head~2 and then git push -f.
