[MIRROR] Most materials can be used to build most things [MDB IGNORE] (#13202)

* Most materials can be used to build most things * Fixes the merge conflict * Makes it so our vis_overlay1 is initialized first. It's awful but it works * Properly fixes the CI issues with the plasma airlocks Co-authored-by: Y0SH1M4S73R <legoboyo@earthlink.net> Co-authored-by: GoldenAlpharex <jerego1234@hotmail.com>
