Unarmed should count as Martial Weapon for the sake of Spirit skills

Currently leveling a pathfinder, playing around with concoctions, which now require you to be unarmed on at least one weapon set. However, unarmed is not considered a martial weapon.

This means that you cannot use heralds (herald of plague for poisonous concoction, herald of blood for bleeding concoction, etc etc...). You also cannot use things like Wind Dancer, cause it also requires a martial weapon somehow.

This basically prevents pathfinders from using most spirit skills that would be useful to them. This wasn't the case before because you did not need to be unarmed for concoctions, but now you do, and that's one more layer of nerfs that I did not see until it hit me.
