Assorted rock behaviors (#2273)

## About The Pull Request

The weird smoothing interaction between bauxite/schist/indestructible
ice walls & other walls was hurting my brain, so I fixed it

Caught some other rock wall related stuff when I was at it.
Notably, Indestructible Rock Walls now have the new, smoothed sprites,
mappers rejoice.

<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->

## Why It's Good For The Game
Crumch.. I love mineral...

<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding. -->

## Changelog

:cl:
fix: polishes out some weird smoothing interactions between some rock
walls and metal walls
tweak: indestructible rock walls now have the new, smoothed sprites
tweak: beach rockwalls now have a whimsical name & description, matching
our other rock walls.
fix: removes the junk 'asteroid' subtype of mineral/random

/:cl:

<!-- Both :cl:'s are required for the changelog to work! You can put
your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
