MA & weapon-block fixes

OK, I've got the text for ZQ up and am working on Crane.  Broke to get the weapon-block trial shot up:

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.  ;-) )
