Load power granted trains from item_power_action instead of static_power_powergrant

Amount = power_arguments[0] of each power type's first action, keyed by
SBStringHash(power_type). Parity (scripts/p28.py): 69 of the 70 DB runes
match; Wizard 2521 WIZ-064 Conjure Familiar goes from 1 to 20 (decided JSON).
The JSON adds grants on 2189 runes: mob and guard races (2100+), Archon 2018
(ARCHON-001..005 40, CSR-UNINVIS 30), and NPC trainer/guard talents
(252569-252655, 253002). Only Archon is a player race; the talents are not
player runes. The DB loader stays until 2.11.
