Mercenaries

[bad_captain]

From the changelog:
REQUIRED SQL: utils/sql/svn/2383_required_group_ismerc.sql -- adds ismerc column to group_id table
OPTIONAL SQL: utils/sql/svn/2380_optional_merc_rules.sql -- Contains rules for mercs including rule to enable mercs
OPTIONAL SQL: utils/sql/svn/2380_optional_merc_merchant_npctypes_update.sql -- Contains npc_types & spawn updates for merc merchants in PoK
OPTIONAL SQL: utils/sql/svn/2380_optional_merc_data.sql -- Contains basic merc data, template info, & merc merchant entries
OPTIONAL SQL: utils/sql/svn/mercs.sql

Do them in that order. Actually, you just need to do 2380_optional_merc_merchant_npctypes_update.sql before 2380_optional_merc_data.sql, before mercs.sql

The rules one and isMerc for group_id can be done whenever.
