Object spell system v1.1

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.
