2561  * You may only fire items that "match" your missile launcher.
2562  *
2563  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2564  *
2565  * See "calc_bonuses()" for more calculations and such.
2566  *
2567  * Note that "firing" a missile is MUCH better than "throwing" it.
2568  *
2569  * Note: "unseen" monsters are very hard to hit.
2570  *
2571  * Objects are more likely to break if they "attempt" to hit a monster.
2572  *
2573  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2574  *
2575  * The "extra shot" code works by decreasing the amount of energy
2576  * required to make each shot, spreading the shots out over time.
2577  *
2578  * Note that when firing missiles, the launcher multiplier is applied
2579  * after all the bonuses are added in, making multipliers very useful.
2580  *
2581  * Note that Bows of "Extra Might" get extra range and an extra bonus
2582  * for the damage multiplier.
2583  *
2584  * Note that Bows of "Extra Shots" give an extra shot.
