Add a way to "Trim" the brown overlay part off of leather armor.

In the newest snapshot they allowed armor trims onto leather armor. I think it would be neat if there was a way to remove the brown part that all leather comes with (the stripe across the head, the caps on the knees, etc)
This would NOT count as a trim, meaning you could still add an armor trim over the blank leather armor. However it could use the same system. Perhaps some kind of forging template, or a different item entirely (maybe just one piece of leather?) would work great. Then we could finally have non-armor pants in Minecraft without those kneecaps.
