Create a README

[silverhook]

A README would be very useful to know a bit more about this project.

For example: a short description and goals, what are the differences between telepathy-gabble and telepathy-nonsense, which XEP are (to be) supported, how to contribute etc.

Any news on it?

A long time ago, I have create this issue: TelepathyIM/telepathy-gabble#8

And there are now XEP-0412: XMPP Compliance Suites 2019 ;)

Do not forget: SCRAM!
