Remove deprecated registerPyAction/registerInputAction system (closes #2, closes #3)

This is our largest net-negative commit yet\! Removed the entire deprecated
action registration system that provided unnecessary two-step indirection:
keyboard → action string → Python callback

Removed components:
- McRFPy_API::_registerPyAction() and _registerInputAction() methods
- McRFPy_API::callbacks map for storing Python callables
- McRFPy_API::doAction() method for executing callbacks
- ACTIONPY macro from Scene.h for detecting "_py" suffixed actions
- Scene::registerActionInjected() and unregisterActionInjected() methods
- tests/api_registerPyAction_issue2_test.py (tested deprecated functionality)

The game now exclusively uses keypressScene() for keyboard input handling,
which is simpler and more direct. Also commented out the unused _camFollow
function that referenced non-existent do_camfollow variable.
