B4003 - exercising spell skills

The spellcasting code stopped counting a spell class's skill
exercise once that reached expert, so the only way that it could
end up being flagged as having reached maximum in the #enhance
feedback would be if it had already received enough exercise to
reach the hypothetical level beyond expert while it was still at
skilled or less.

     It also didn't count the exercise if you were restricted in
the spell class, but that wasn't necessary because becoming
unrestricted--which I don't think is even possible for spells at
present--resets the counter back to 0 to discard any exercise
achieved while ineligible.
