Version 1.2.1

General wording pass across the PDF document, with some minor tweaks to actual optionals:

• Field Gun Carriage now has Loading tag (as was originally intended). Clarification on how set up/pack up works and how it impacts weapon functionality - cannot be fired unless set up.
• Gun Emplacement can now choose to move 3 spaces instead of attacking - gives some room to roam, but also can synergize directly with Entrenchment Tools now.
