AI spell casting priorities

[Twan]

Summon imp seem to get too much value.

In a game with Utgard I sent a lone werewolf with a slave scripted to cast quicken self, breath of winter and then reinvigoration, to start the melee without fatigue.

He overwrited breath of winter to cast summon imp, getting 102 fatigue (by chance his natural reinvigoration allowed him to recover and win against the weak ennemy PD, but with more opposition it would have been sure death) .
