Makes the steel pipe slightly less awesome as a weapon.

This thing had stats that were comparable to a real weapon.
Adds missing weapon flag to razorbar katar.
Fix incorrect requirements for bio_face_mask
Changes POCKETS and HOOD to respect temperature.

Now the character will only use the pockets and hood for their warmth
bonuses if their hands or head are actually getting cold.
This solves the problem of characters who are perfectly comfortable
automatically sticking their hands in their pockets or wearing their
hoods and then getting hot head/hands as a result.
Merge steel pipe nerf and razorbar katar fix.
Merge pocket and hood usage fix.
Merge bio_face_mask recipe fix.
