[Suggestion] Mark "Unused" sprite sets

[TsukiZero]

To make it easier to spot unused sprite sets, how about adding a background that makes it stand out from the rest, so that we know we can use that entry to add new sprite sets?

Also, worth noting entry 17 in weapon sprite sets is Bare Handed ("----", in a sense), but is marked as unused.

darkfunction Editor can already do that

Not what I meant, I meant in the Sprite Editor in DSVEdit. More specifically these:

As you can see here, there is more free (Unused) Sprite Sets now that I did a thing to condense multiple animations to one GFX and Sprite set.

And, well, as you can see entry 17 shows Cestus and Illusion Fist uses it, but is not showing that Barehanded (empty slot or "---" in the game) uses it as well (defaults to animation set 00)
