Feature/fancy terrain

Updated Terrain Generator

The current terrain generation was unplayable as the world consisted of isolated islands within a void. The terrain was lackluster as the surface was only composed of dirt and grass. There was no incentive for the player to explore the world or mine into the depths below. This PR addresses this issue by completely overhauling the generator and by adding various development tools along the way.

#47

Goals

• Terrain is less shitty then it was before
• Density based terrain with overhangs, cliffs and valleys
• Ridged height map
• Spaghetti caves
• EGUI interface to control various generator parameters with quick feedback cycle
• Feature flags for all added dev tools

Optional Goals

• Basic Iron ore distribution
• Sediment distribution (andesite / gravel / dirt)

Unrelated changes

• Chat feature flag
• Player controller feature flag

Developer Tools

• EGUI interface for the server to adjust splines, noise function parameters, update terrain
• Orthographic camera
• Flag that prevents generator from setting padding blocks
