PubSub system (#346)

* Add websocketpp dependency

* Initial pubsub commit

Renamed selection min and max variables to selectionMin and selectionMax
to bypass windows min/max macros being stupid.

TwitchAccount is now initialized with its User ID. It cannot be changed
after it has been initialized.

* Update openssl folder

* Update installation instructions

* Split up websocketpp dependency to its own code only and openssl.pri

* Add missing include to asio steady_timer

* Update dependencies for linux
