Add separate TotalRounds var for Lua to count the *actual* number of rounds that have been played The internal TotalRounds (now TotalRoundsPre) is really WTF to use from a Lua standpoint and rarely useful. Scripters usually want to know the real number of rounds.

Directory for automated tests to test the engine.

Run `ctest` in the root directory of this repository to run all tests.
Run `ctest -R <test name>` to run only the test with the given name.

This requires you to have CMake.
