Updated for 07-Sep-2021 update

Added custom build menu icon, upgrade icons now show correctly, now has 3 upgrades 1 standard vaporator, 2 removed breakthrough tech as it doesn't seem right to stop people having access to such an important upgrade but reduced to +50%, 3 turbo 5x boost 10x maintenance build up. Dropped to 2 base output to be closer to vanilla version. Other minor code tweaks.

Proof of concept.
Will need updating and upgrading to better balance and decide whether it should be an upgrade or hard coded feature to resist dust storms
