Beware with Heroku deployments

[pataquets]

Heroku terms forbid p2p:
https://www.heroku.com/policy/notices-and-license
My account has been suspended (when trying another p2p software).
I've had to go thru the unblock process and learnt it along the way.
Either place a warning or remove the Heroku button completely (the latter, the safer, IMO).

I also noticed, that Heroku automatically blocks some P2P services. Previously it also blocked this project, the culprit was mafintosh/torrent-stream.

Removing the Heroku button would be a shame because it's a very easy way to test this project. Plus Heroku doesn't block this project at the moment, I am running this project for a week and it works well. Moreover works well with a free tier and if it suspends the free tier it's now a bad thing. But I recommend creating a new account for it.

I added a warning below the button.

We should think about deployment alternatives. Heroku paid is quite expensive and doesn't support P2P. Maybe we should create a tutorial how to setup on VPS and suggest VPS provider.
