Port and tweak from World Server of their weight and body type system
Removed the current size trait system for player mobs.
Replaced with the weight and size system from world server.
Mobs with heavier body types will be slower but have a higher metabolism.
Mobs with thinner body types will have a slower metabolism and are more fragile.
Being tall or short has no effect aside from the sprite.
Couple weird quirks (sprites are a lot more fuzzy compared to world server, and lying down sprites can look slightly off) but overhaul seems usable.
Adds four types of colorblindness to the traits in the setup menu - protanopia, deuteranopia, tritanopia, and monochromacy. Previously, there were ones defined in the code, but not actually usable to players.
Scaling wasn't great before so no Again.
Makes most icons not get blurry when scaled.
Makes all /atom/movable s able to be scaled with the adjust_scale() proc.
Adds ability for species to get scaled automatically. Currently no species does this, but it is an option in the future.
Adds four traits to adjust your mob scale. It is purely cosmetic at this time.
