unimply bow from crossbow

BUR #4564 has been approved by @evazion.

remove implication crossbow -> bow_(weapon)

Was done in topic #1926.

They're two different things, this implication makes no sense.
Once it's approved someone will need to go through all posts and fix the mistags. Also removing holding bow (weapon) from holding_bow_(weapon) crossbow where applicable and replacing it with holding crossbow.
