Immersive Aircraft: Better Engines

• New fuel item: Compressed fuel! Made from lava and coal blocks(which can now be made from charcoal), it allows for a nefficient fuel solution!
• Boiler upgrade: We now have the advanced boiler, which is a better version of the steel boiler, giving more power but also more fuel usage. Cant use 2 boilers at once.
• Brought back the reinforced engine as the advanced engine! A middle-man upgrade between the stock engine and the nether engine, to improve engine progression!
• Brought back the semi eco engine! A middle-man upgrade between the stock engine and the eco engine!
• Greek translation!

Forge build having issues, will take some time to be out
