Refactor item handedness code

Instead of specifying HANDS_ONE or HANDS_TWO in Weapon_prop[]
(which were... misleading at best), there's now a min_2h_size
and min_1h_size field. The former controls the minimum size a
player or monster must be to wield the weapon at all; the latter
is the minimum size required to wield it with one hand.

This means that giants can now wield daggers (unlike before);
if necessary, a max_size field can be added, but this seems a
low priority to preserve.

This breaks formatting of Weapon_prop[] a bit; apologies.
