Essential Structures

Marked as "beta" even though it should be fully functional. Just not my entire vision, also somewhat not optimized.

added "raft" with 8 variants. (a raft in the ocean). added "portal" with 9 variants. (different types of nether portals, unfinished, ruined, overgrown etc.) added "desertscape" with 5 variants. (dead tree) added "tower" with 5 variants. (a brick tower with spawners and hidden loot.) added "snowy" with 4 variants. (small igloo with snow.) added "divingbell" with 2 variants. (an underwater safe haven to breathe and sleep if need be.)

-Changed all weight values to either 1 or 2 to hopefully make it more random and even odds of spawning different varients each time. -Tweaked all spawning chances (average and minimum chunk distance) to hopefully make it more balanced. -Randomized the index numbers for all structures to hopefully make it more spread out and not overlap.
