Documentation issue with SDL2 code

[raysan5]

Hey! Thanks for the raylib implementation and the great documentation.

Just noted an issue with SDL2 Tile Layers Code, it's Allegro code instead of SDL2.

Also, on the Initial Setup code for raylib you are including <stdlib.h> and <string.h>, those libraries are not required.

:)

Thanks, I'm bad at copying and pasting :upside_down_face:

Header <stdlib.h> is providing function declarations that are used later in the tutorial (malloc and free), but at that step it is indeed useless. Header <string.h> will be removed.
