v0.06 Dev/Balance/Art Update

!! Resized the MP7 and USP Match because they were too out of scale with
the rest of the sprites. Guns in RimWorld are a little oversized for
readability, but they were just way too giant.

+ Beatrice rebalanced most of the gun pricing again, and some weapons
cooldowns/warmups were tweaked.

+ Armor is being rebalanced finally, and pulse burn resistance was added
for select apparel. It's still harder to block than gunshots.
