[dev1033] Class name changes

[Cairdeas]

Naoki Yoshida has stated that the development team is deciding between two options.

1. Jobs become "specializations" within existing classes (i.e. a Gladiator can specialize to become either a Paladin or a Dark Knight).
2. Jobs become "advanced jobs" in addition to existing classes (i.e. a Gladiator or Marauder can become a Dark Knight).

What we've been discussing thus far in several threads is which should be implemented, how either could be implemented, or whether any should be implemented at all.

I vote Option 2
