TechRacer: Fix gears not spawning on turn start when player pressed control right at start
The activationStage was horribly programmed and heavily relied on timer. There was a sweet spot
at turn start that if you managed to push a key right at the start of turn, you skip the Ready
phase and the activationStage would advance, causing the gear spawning code to be skipped.
This fix greatly simplies the spawning phase.
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.
