Move guard captain powers from static_rune_powers to MinionType

The 14 Magister Captain contracts' powers have no client rune or deed
(Task 3.9), so they live on the MinionType mage entries instead of the
DB fallback in loadAllRunePowers. canCast, mobCast and aiInfoCmd read
them through MinionType.getCaptainPowers.

No value change: same 56 power ids, rank 40, and all 56 DB tokens equal
the powerbase token of their power id (checked on mbdb_108).
