Stop creating firmware version objects in GCS_Dummy

[peterbarker]

This was always a bit of a nasty kludge, and gets in the way when you're trying to sometimes have a GCS in your firmware and sometimes not.

So instead of having the dummy do it, include a file into the cpp which accomplishes the same thing.

Only affects examples, unit tests and Replay.

i like making tests to be as easy as possible, and with each of these extra bits of bookkeeping requirements it makes it a bit harder. I'd prefer to move towards having less of this type of thing in every test
