Game update

• Rewrote the map generation algorithm completely. Size is still limited, but editable.
• Made foliage & tree generation percentage alterable.
• Created new foliage & tree variations for each biome, being:

• Dark Forest (3 tree variants, 3 mushrooms)
• Snow (2 tree variants, 2 foliage, 1 rare snowman)
• Desert (dead tree, dead bush. Don’t expect to find anything there!)

• Redesigned the infotext. You can still press C for some information.
• Optimized performance for larger maps. Too many objects will still affect performance, but render distance is now editable.

This release also features the amazing friendlyscribbles font by kmlgames!
