 * You may only fire items that "match" your missile launcher.
 * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
 * See "calc_bonuses()" for more calculations and such.
 * Note that "firing" a missile is MUCH better than "throwing" it.
 * Note: "unseen" monsters are very hard to hit.
 * Objects are more likely to break if they "attempt" to hit a monster.
 * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
 * The "extra shot" code works by decreasing the amount of energy
 * required to make each shot, spreading the shots out over time.
 * Note that when firing missiles, the launcher multiplier is applied
 * after all the bonuses are added in, making multipliers very useful.
 * Note that Bows of "Extra Might" get extra range and an extra bonus
 * for the damage multiplier.
 * Note that Bows of "Extra Shots" give an extra shot.
