Load the NPC guild seed on the login server

Character select sends each character's guild, and since 2.8 the NPC
guilds exist only in maps/<map>.guild. The login server loaded guilds
from the DB only, so characters in NPC guilds showed as errant. It now
loads the seed guilds first, as the world server does; a seed that fails
to load fails the login server boot.
