Archive the repo since it's inactive

I think that it would be better to inform folks that this project is more or less dead by archiving it.

Waiting for @pardahlman to provide information about the future of this project.

It is ashamed. This project actually looks pretty cool. It gets some cool features that EasyNetQ doesn't have.
