Update 0.4

Not much new yet. Mostly new textures and a few new models.

Textures that's new:
 1. The sea.
 2. Sand.
 3. Grass.
 4. The sky. (Probably getting a makeover pretty soon.)
 5. Palm tree. (Definitely getting a new one soon. and also a new model that looks a bit more like an actual palm tree.)
 6. Darings texture is switched with a more complicated one that almost looks different from the old one.
