Subject: [PATCH] Parse table/Server/DungeonScaleStat.xml

The server table carries the same scaleStatRate, scaleBaseTap, scaleBaseDef
and scaleBaseSpaRate attributes as the per-NPC scale* stats, one row per
dungeonScaleStatID. No dungeonroom column references it in the NA or KMS2
data, so a server that wants per-dungeon stat scaling keys its own rows on it.
Bumps the package to 2.4.29.
