Removed GLFW leaks

[XEDGit]

Leaks list
mlx_init.c:

• 84: glCreateShader(type)
  The shader was not being deleted correctly, it has to be detached
  before being deleted, the documentation says you only need to use
  glDeleteProgram and they'll be detached but from my tests it is
  not true

• 120: glCreateProgram()
  The shader program wasn't being deleted at all with glDeleteProgram

• 124: glLinkProgram(mlxctx->shaderprogram)
  I have very hard time understanding the underlaying system, the docs
  don't make any reference to it, but calling again glLinkProgram
  before deleting shaderprogram frees the leaks generated from the first call

• 88: glShaderSource(shader, 1, &code, &len)
  I figued out the leak consists in the copy of the code allocated for the shader
  but I could't understand how to free it, apparently glDeleteShader doesn't take
  care of it
  New mlx_terminate with modifications:

void mlx_terminate(mlx_t* mlx)
{
	MLX_NONNULL(mlx);
	mlx_ctx_t *const mlxctx = mlx->context;
	// to add for leaks
	glUseProgram(0);	// removes shaderprogram from context
	glLinkProgram(mlxctx->shaderprogram); // frees memory allocated earlier by same function
	glDeleteProgram(mlxctx->shaderprogram); // deletes shaderprogram
	// end
	glfwTerminate();
	mlx_lstclear((mlx_list_t**)(&mlxctx->hooks), &free);
	mlx_lstclear((mlx_list_t**)(&mlxctx->render_queue), &free);
	mlx_lstclear((mlx_list_t**)(&mlxctx->images), &mlx_free_image);
	mlx_freen(2, mlxctx, mlx);
}
mlx_init_renderer, add these lines after deleting the shader:
glDetachShader(mlxctx->shaderprogram, vshader);
glDetachShader(mlxctx->shaderprogram, fshader);

Seems legit to me, I was under the impression that mostly delete should take care of it but I guess I was wrong?
