Added a direction finding algorithm for target, get_dir_to(). Mostly useful for positioning sprites in relation to a target. Such as energy beams, lines, and so on.
Changes to ninjas. Fixed a bunch of bugs and finished content. It is now possible to drag people with you when phase jaunting/shifting. Jaunting/shifting should also kill livestock, huggers, and damage mechs.
Renamed /obj/spell path to obj/proc_holder/spell in order to have a generic proc_holder category. For now it only works for the AI but can be expanded to other mobs.

Completely revamped the classes, it's even more streamlined now. Got a few bugs and tweaks (namely, blind doesn't work, fireball got buffed up as compensation for not dealing additional damage to the target), but it's okay, since nobody uses those anyway.
Fixed the bug with emagged borg laws.
