I've made minor updates to all the rule books. Fixes include spell checking, adding Afghanistan to the demographics chapter in the core rules, adding missing hull capabilities to the gas giant atmospheric depths table and extending the flight altitudes table for depths below gas giant aerostats in A Facility with Words, and adding O & B stars to the system map designer appendix in A Lot of Zeroes.

I've also moved the infrastructure chapter from the core rules to the This Space Intentionally supplement. I will be including this chapter as an excerpt from this supplement at a later date.

I've pushed this up now because of the inclusion of the game in an upcoming bundle and some marketing initiatives that should be happening in early February.
