Proper Error/Exception handling

The entire simulator could use a proper error handling concept that would be used throughout all simulator projects.

Goals:

• Describe a concept for designing exceptions and how they are propagated through the simulator.
• It has to support exceptions occurring remotely (autopilot, remote server) as well as in other languages (ex: c++ for the hardware_emulator)
• Ideally a comprehensible stack trace would show additional contextual information at different points in the call/catch stack.
• List all the errors (that are relevant to a user) and define a system to properly notify them.
• Define a system to properly notify exceptions (bugs/missing features).
