- Fixes Issue 910

- Changed mineral walls, they have their own type by mineral instead of a variable
- Now you can spawn the different mineral walls with the game panel
- Fixed the examining in walls, they will now show the text on the 'desc' var

 There are still some stuff out there with mineral walls, ugly chunks of code that does the same thing, two vars that have the same value and stuff like that. All of that will be purged, but, as always, to be continued~
