Spiked chain in weapon hand slot messes up weapon descriptions

[Stone Dog]

Whenever I'm holding a spiked chain in my weapon hand, every other weapon (even those picked up from the ground) has in its description "Closing with you when you wield this weapon requires a reflex saving throw against DC x". Putting the chain in every other slot (even the off-hand one) removes this snippet of text from other weapons' descriptions.

Whether a creature has reach is a global flag, and all weapon descriptions were annotated using it. Now weapon descriptions are only annotated as having reach if they have reach, otherwise if the creature has inherent reach for physical reasons. Closes #62
