re-enable weapon blocking??

Not sure whether Nature's Witness was onto something but I was right
there and could make the change.  Unless swwu tracks arm blocking and
weapon-blocking together, I'm not sure why arm-blocking would be
necessary.

(Yes, I know this is the same methodology used by Pet-A-Kitten.  I don't
claim to be a good coder.  ;-) )
ZQ & Crane: Understanding check

Now, I don't know where the tech-definitions are supposed to happen, nor
whether what I did for Crane makes sense.

Guidance will be appreciated.  Help me help you!
