The following error occurs twice:
```
mqtt/qmqtt_ssl_socket.cpp:49:13: error: static_cast from 'QAbstractSocket::SocketError (QAbstractSocket::*)() const' to 'void (QSslSocket::*)(QAbstractSocket::SocketError)' is not allowed
```
It may not be the cleanest fix but the it is the only one I could come with...
library that I was able to integrate into the codebase so there aren't any external
dependencies. Both external projects have their own open source licenses. Those licenses
are included. Also in this commit is some preliminary work to start adding MQTT support to SavvyCAN.
