Take power target types from Powers.cfg

PowersBase gets setTargetType (the old inline parse, now resetting the
flags first) and the world server re-applies every power's target type
from PowerTemplate after the wpak load. The login server only uses power
tokens and keeps the DB value.

Parity vs static_power_powerbase (1465 powers): 1460 identical, area,
radius type, exclude and target effect prereqs identical for all.
Value changes:
- NEC-018 Sepulchre's Bounty: PET -> MOBILE. Its AoE now collects mobs
  and pets; the NECROPETSTATS target prereq keeps only necro pets.
- DRU-066 Braialla's Judgement: NECROPET -> PET.
Kept on the DB (user, behaviour change, for the Phase 4 power task):
HLR-025 Succor PC (cfg CORPSE), HNT-023 Phaedra's Fury PC (cfg SELF),
RNG-033 Fleet of Foot GROUP (cfg SELF).

Client: ArcPower_IsValidTargetForType 0x49E440 accepts any live
ArcMobile for Mobile and has no case for Pet (server decides).
