Update 0.30.4: News and Contracts!

• News! This is the first major use of procedurally generated text in the game. I also added some text generated by GPT-2, which was a fun experiment.
  
• Contracts! This is one of the major gameplay elements, and in testing and tuning it, I started to feel like I was actually playing a game. The idea is that the player can weigh the cost versus the sustainability. I also added images and some flavor text.

I'll doubtless be tweaking these features as I move on.

Behind the scenes, I also added Encompass, which has been really nice to work with. It did require some rewriting of existing code (mostly input handling), but it has left the code base easier to work with. I don't know that ECS (or MECS, I suppose) is The One True Way to architect video games, but it is One Good Way.

I also added logging (as in error log, not a logging company game mechanic). Ironically, my goal is that players don't see the logging because it means something went wrong. I'm pretty happy with how the logging works—it takes things I like from Python's logging module and Glögi, a Clojure(script) library I use for work, and puts them in a convenient package. I'd like to incorporate some ideas I got from Handmade Hero's debugging system, mainly performance counters.
