przywrócenie trybu wydajności (jako komentarz), uprzątnięcie kodu

- Makefile uwzględnia glfw
- projekt w visual studio także powinien linkować glfw
- dodano plik .gitignore
- klasa lazik stworzona z myślą o łaziku
- bliźniaczo podobna klasa plane stworzona z myślą o mapie
- dodano surowy projekt mapy (res/models/mapka.obj)
- usunięto zbędną klasę sześcian oraz plik wykonywalny .exe
- funkcja timestampedCout() przeniesiona do plików timeh.cpp/.hpp, co pozwala na używanie jej wszędzie
- w main.cpp:
	- zakomentowano masę (niepotrzebnego)/przeniesionego kodu
	- tryb monitorowania wydajności wyłącza ValidateRect(), co wymusza ciągłe renderowanie nowych klatek. pozwala to oszacować wpływ zmian na wydajność programu.
