New spell: Spellforged Servitor

With the idea of introducing more summoning spells that a bit
unique in some way, this is a level 7 Summoning/Conjurations spell
which summons a single golem-like being that possesses a subset of
the caster's own conjurations.

The spell list is assembled deterministically, somewhat similar to
player ghosts (though different in a number of regards). The first
3 spell slots draw from a 'primary' list containing direct
conjurations like bolt of cold or poison arrow, while the next 2
are from a 'secondary' list which tends to contain AoE effects and
cloud spells, as well as things like airstrike. Spells are selected
roughly in order of level and power, with the player's higher spell
skills having a small effect. In practice, I think the servitor
will fairly transparently possess a selection of the player's better
spells, without anyone needing to think much on how it arrived at
this list.

Many of the highest level spells (like fire storm and shatter) are
excluded not only for power reasons, but also because a servitor
using these could be downright dangerous to its caster. The main
exception I made here was CBL, which is allowed (being both
lower-level and often similarly dangerous when the player uses it,
though I open to changing this).
