Priorities system

[impyre]

Just wanted to give props to Klei. Where the priorities system came from, and where it is now... it's great. It's a marvel of modern engineering for sure. Somehow the system works like they wanted it to *and* like most folks expect it to. "sub-priorities" are a bit less "sub" now... at least for extreme values so you can actually use the sub-priority marking to designate high-priority override tasks, but somehow still work as intended for median values (hey, dupes... if you got two algae terrariums which both need filling... fill the one in the base first). It really is a thing of beauty.
