- Converted Devil and Wand fireballs as well.
- Moved some code to the /proc_holder level to work across the /alien
and /spell branches.

* Tweaks and Fixes

- Infernal Fireball is now a projectile and has the right explosion
values.
- Removed non-projectile spell versions of fireball, as they are unused
- Fixed fireball not seeking adjacent targets.
- Fixed incorrect bolding slashes.

* Fix

Fixes the fireball sometimes missing.

disabled state. (Such as being knocked out)
