Remove the static_npc_mobbase_effects loader

Mob effects come from the race rune (2.10b builder) and necro pets get
NECROPETSTATS in code, so GET_RUNEBASE_EFFECTS, the MobBaseEffects
ResultSet constructor, its unused mobBaseID and the equals/hashCode used
for the merge are gone. The table is now unread; drop it with
sql/3.4-mobbase-effects-drop.sql.
