Apprentice update

[Reijin]

Also, there is now the [Apprentice Saga] prefix available on the Namek-sei, Heaven, and Hell boards. If it is needed on any other planets for the purposes of the sagas let me know, but I believe that covered it.

I changed Krillin's [Staff Saga] setting to it.

Noone other than Apprentices are allowed to use this prefix, just like the [Staff Saga] one. Sankyu.
