New spell: Summon Mana Viper

With the aim of creating summons that have more differentiated uses
from each other, this spell summons something that can provide good
anti-caster support while being less directly mighty than other
higher level summons, particularly against enemies where its antimagic
bite contributes little.

It is a level 6 summoning/hexes spell which summons a mana viper (with
a cap of 2) whose antimagic effect scales noticably with spellpower,
but its hp and damage do not. The general idea is that it is less
good at killing many things on its own (and spellpower alone cannot
turn it into something very tanky) but an investment in the relevant
skills can provide a very strong augment against vulnerable enemies.
(It IS still pretty strong even against non-casters, I admit, but also
a level 6 dual-school spell with a less common secondary school, so
maybe is fine as-is).
