Allow Class Change

Removes the level 20 requirement to change classes of a character. It feels silly that you are stuck as a class till level 20, if your a mage you need to master magic to become a swordsman? Why? If it was a case of swordsmen to master swordsman or some other advanced classes sure. But that is not the case so the level requirements don't make any sense.
