2811  * You may only fire items that "match" your missile launcher.
2812  *
2813  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2814  *
2815  * See "calc_bonuses()" for more calculations and such.
2816  *
2817  * Note that "firing" a missile is MUCH better than "throwing" it.
2818  *
2819  * Note: "unseen" monsters are very hard to hit.
2820  *
2821  * Objects are more likely to break if they "attempt" to hit a monster.

2823  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2824  *
2825  * The "extra shot" code works by decreasing the amount of energy
2826  * required to make each shot, spreading the shots out over time.

2828  * Note that when firing missiles, the launcher multiplier is applied
