Makes mineral walls smooth with each other

[CRUNCH-Borg]

What Does This PR Do

Makes most mineral walls smooth with each other (Wood, uranium, gold, silver, sandstone, plasma, diamond, bananium)

Deletes the smoothing groups for these mineral walls and consolodates them under the SMOOTH_GROUP_MINERAL_WALLS group.

Puts rock turfs under the new SMOOTH_GROUP_ROCK to free up the above smooth group for this operation. The naming schema makes more sense this way.

Why It's Good For The Game

These sprites are designed to smooth together but the code was not changed to allow it to happen.
