Overlays for Blocks

MCreator should have a feature called "Block Overlay." Essentially an overlay for a block, like a sign but instead of text it's an image.

Just click the "+" button, and then click "Block Overlay."

Name the overlay, choose the texture(s) for the overlay, and then you created it!

In procedures, you should have a code block that says "change block overlay to:" and you can change it.

You should also be able to apply multiple overlays to the same block.

This saves time to create all of the textures for one block.

I hope this gets added!

(also there should be a 3d block overlay which basically merges the models of 2 blocks to make custom blocks easier like flower pots)
