Refactor TSNRESTObjectMap

[thomassnielsen]

• Remove all user visible mutable dicts ([Perf] Refactor to make ObjectMap dicts not mutable #18)
• Add unit tests
• Automapping (Make object mapping more automatic #5)

I've started adding tests, although I don't feel that the test set is complete. Right now I basically only have tests for the automapping.

Removing the boolean part of this task - it won't work, as we can't determine if we should send 1 or true when serializing. We could do runtime check when deserializing, but that wouldn't matter.

It's way better than it was, and we have some basic testing in place as well.
