DA Concrete Expansion

Preparation for 26.50.

When 26.50 is released, this addon will automatically:

• replace any concrete single slabs or stairs in your inventory with the new, vanilla slabs/stairs. All you have to do is move them into your (player's) inventory slot, or if they're already in inventory, move them from one spot to another, and the item will be automatically replaced.
• replace concrete single slabs and stairs in the world with the new, vanilla slabs/stairs when they "tick". if you have an area with a large number of slabs/stairs, just hang around for a bit and they'll all eventually change.

In the meantime, you can continue to use this addon as you always have, without worrying about having to replace all of your placed blocks at some point in the future. :)
