2563  * You may only fire items that "match" your missile launcher.

2565  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2566  *
2567  * See "calc_bonuses()" for more calculations and such.

2569  * Note that "firing" a missile is MUCH better than "throwing" it.
2570  *
2571  * Note: "unseen" monsters are very hard to hit.
2572  *
2573  * Objects are more likely to break if they "attempt" to hit a monster.

2575  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2576  *
2577  * The "extra shot" code works by decreasing the amount of energy
2578  * required to make each shot, spreading the shots out over time.
2579  *
2580  * Note that when firing missiles, the launcher multiplier is applied
2581  * after all the bonuses are added in, making multipliers very useful.
2582  *
2583  * Note that Bows of "Extra Might" get extra range and an extra bonus
2584  * for the damage multiplier.
2585  *
2586  * Note that Bows of "Extra Shots" give an extra shot.
