Since there is a new version of GearsBot using the new command-based
API, the old GearsBot is just removed.
PR #1842 is being included to verify this PR is correct.
This is the C++ version of #1682.
The old command framework is still available, but will be deprecated.
Due to name conflicts, the new framework is in the frc2 namespace.
Eventually (after the old command framework is removed in a future year)
it will be moved into the main frc namespace.
Also checks that all items in the json file have a matching example
One was missing from C++, that example was added (The one in eclipse was completely wrong)
