Gunslinger & Spellblade Edits

Gunslinger got a few important fixes to gear (for example, pistols no longer have their baffling close range and are just near, and also the Gunslinger has ammo, which seems important). Also edited Gunsmith so that the Gunslinger can make guns and ammunition, since that seemed like a nice quality of life fix. Spellblade got some minor changes to moves, most notably to Make History so that the last option is a little more interesting.
