wrote a few tests to make sure the claymore is working
implemented new phrases for claymore behavior
refactored weapon aftereffects test a little
Refactored scythe of oxidation, with some unexpected results #341

My new phrase, "whatever (the item) hit" does not consider weapons
to have touched each other if the global attacker weapon is ranged.
This affects what happens with the chain golem, whose weapon
is ranged, but presumably its "ammunition" remains in contact with the
weapon. Discussion is needed to determine the correct behavior.
removed debugging code
Added a variable to keep track of whether the attack hit.
Made a nicer phrase to decide whether "the attack hit." #341 #332
Removed debug code from sensing Isra and Fell test
Added greasy gauntlets tests to weapon aftereffects tests
Fixed scythe of oxidation so it can rust the lashing chains when parrying.

Changed weapon-contact phrase to "struck" instead of "hit," and added
a new phrase to decide whether a "striker struck the stricken"
Fleshed out weapon aftereffects

Added some new phrases for testing weapon interactions
Expanded weapon range to hand-to-hand/tethered/projectile
Added a couple new aftereffects tests
