[PnP] Phoenix magics + Ap

[Alex Koponen]

Someone said that they suggest switching W and Em as the prime attributes
for shamanic and sidh magics. I second that idea.

Another idea is to have a new category of  Bardic magic based on
Eloquence, maybe some spells getting a bonus from Ap.

Speaking of Ap, I am not fond of it having its own progression table. I
would prefer if it shared the progression that other attributes have.
