/*
* Fire an object from the pack or floor.
*
* You may only fire items that "match" your missile launcher.
*
* 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.
