Change video.c prepare for 24bit screen.

Check loadingbg[#][0] when call lifebar_colors.

video_set_mode will need 3rd paramters, specify pixel bytes count.

lifebar_colors and standard_palette should be called once before update_loading. Since the method reads file and should be very slow.

Drawmethod should be copied, not reference the frame's drawmethod or entity's.

All sprite method use s_drawmethod to clean up the code.

Remove is_flip property from s_sprite, use is_flip paramter for sprite functions. This will avoid the complexity of swapping centerx/y.

Put alpha effect back into gfxshadow.
Therefore the sprite queue need an extra property.

Check z at least once when player respawn in a level has same min/max z. So they won't drop in hole.
