[Enhancement] Seesaw and Flag sprites should have spritesets, as they do in SMB1

[villager103]

What i'm talking about are these sprites here:

In SMB1, these change color depending on the enemy and terrain spriteset colors, respectively. The flag uses the same colors as the green koopa/cheep cheeps/1ups, while the seesaw uses the ground tile/bricks colors. For example, in an underground level, the flag would have the brown/blue colors that the green koopa has, while the seesaw would be blue instead of pink/brown.

To prevent conflicts with older mappacks that retexture these graphics, perhaps have the game accept both the current dimensions and the dimensions with the 4 spritesets, and if it has the old dimensions, spritesets will not be supported, or have a way to edit the spritesets in the dropdown menu.
