Allow Escrima, Silat, and Fencing to use more weapons

Nerf Bowling Pins

24 bashing is only a little less than the medieval mace's 26 bashing, and the Bowling Pin is much lighter and therefore faster to swing. Also, official 10-pin bowling pins weigh 3 pounds 6 ounces at a minimum. I changed the bowling axe to keep around the same weight difference between the two. There's no recipe for the bowling axe, but the weight difference is approximately consistent with an added 3 scrap metals.
Allow TKD and Tai Chi manuals to spawn in dojos
