Minor update

This is small update after I've migrated from Adobe InDesign to Affinity Publisher. I used the conversion process as an opportunity to tweak some of the (still very sparse) setting text, bringing it more in line with the seventeenth century Ukrainian cossack state (as opposed to a more medieval princedom).

Next update should be more substantial, as I'm working on some (optional) mechanical changes to the Ironsworn formula. I'm also keen to pack one or two new illustrations in.
