Remove the need for BltPlayerTop

[JokeofWeek]

It already handles the NPC as well. Look at the code xD

I've been meaning to do something like this for ages. I originally had it as:

For y = max_mapy to 0 step - 1

Thinking that it should render from bottom to top. Silly mistake tbh xD

:O True xD Hadn't realized that Although, it's probably the easiest to do in DX8, just set the Z value I'd beleive xD Nice optimization for DX7 though
