0.4: Spaceship, Metals, Planets and BOOM!

Yeah, big update guys! 

• Revamp to terrain generation (AGAIN), so now there are distinctive planet types! They are: ROCKY (small, rocky planets), LUSH (forests and trees), ARID (hot, dry deserts), BIZARRE (strange planets, with strange forests), and WASTELAND (radiated, hot, generally a bad place to be)
• SPACESHIP! A big, tall rocket that allows you to traverse the infinite universe! Anything inside stays there, so you can make it feel nice as homely. Don't worry, theres no-one to tell you to clean it up... 😳
• Explosives! Oh no... A new orange-coloured ore generates on the planets, very creatively named EXPLODIUM! With 2 of this ore, some cardboard, and a flint (from rocks), you get dynamite, and the ability to be the harbinger of destruction. Oh god what have I done.
• Tons of new scatters! All kinds of alien looking trees now generate on the planets, more types coming soon.
• Storms! These enormous columns of rushing air now generate on the planets and serve as a dangerous environmental hazard! They're a bit buggy as they are, but I have a few ideas on making them better, so yeah.
• Full metal progression! Added in all of the metal ores and their respective toolsets finally, so have fun grinding for Titanium!

Probably more that I forgor💀 but yeah, enjoy!

also yeah bugs D:
