Core/Logging: Extend logging system to allow inheritance of loggers
- Changed default loggers and appenders
- '.' determines the relation between loggers ("type.subtype" inherits "type" logger setting if logger "type.subtype" is not defined)
- When core logs a message it search for the correct logger (root is the default one)
  ie: a message logged with "type.subtype"
  * Core will try to find a logger with name "type.subtype", if its not found then will search for "type", again if its not found it will return the default one "root"
Core/CreatureGroups: Calculation change requested by Shauren.
DB/Creature_text: Creature text for Wrath-Scryer Soccothrates
