Rebalance crossbows

Again as a result of the ranged weapons rebalance, crossbows
needed to change. The analogy here is long blades' to bows'
m&f; better return on skill investment & a higher power cap,
but rarer.

Hand crossbows are added as a starting type, "something like an
armour-piercing dagger"; crossbows are upgraded to arbalests
(a little worse than a glaive), and a new rare triple crossbow
type is added on the top end (a little worse than a bardiche,
though with a lower skill cost.) Please note that the triple
crossbow historically existed & is extremely verisimilitudinous.

Hellfire is now an arbalest, and Sniper is now a triple crossbow
(well, a "heavy crossbow", since it has mindelay of 27 instead of
22, and since I didn't want to have to change the sprite).

All crossbows have a mindelay of at least 1.0; this is an attempt
to differentiate them. Possibly something more ambitious will be
attempted in 1.6, but this is a first step.
