Add two new external libraries. SimpleCrypt is used to encrypt passwords, QMQTT is an MQTT

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.
