Load Skills, StartingKitTable, CharCreateRuneList and PowActionCostInfo

SkillParser: uid, name, icon, attribute weights and description per
Skills.cfg line (94 skills; the server's ids 1-63 stay in the DB).
StartingKitParser: each kit line is a list of up to 10 item ids under
its RACE= line, as the client reads it; the file's tab columns are not
used (451 kits, same count as static_rune_validkit).
CharCreateRuneParser: race (with sex), class, promotion and attribute
creation rune lists. PowActionCostParser: resource costs per id, the
source of static_effect_costmaps (524 entries). No consumers change.
