Core/Logging: Try to simplify configuration of loggers and appenders

Changed multiple lines to a simple format:
- Logger.name=Type,LogLevel,Flags,AppenderList
- Appender.name=Type,LogLevel,Flags,optional1,optional2
  * Type = File: optional1 = File name, optiona2 = Mode
  * Type = Console: optional1 = Colors

Created a default set of loggers and appenders.
- Root logger defaults to Error, that means you will see nothing on console by default (not even loading)
- You need to add the loggers to Loggers options if you want to enable them, otherwise Root logger will be used for all types

Restored outSQLDriver (LOG_FILTER_SQL_DRIVER), outSQLDev (LOG_FILTER_SQL_DEV), outArena (LOG_FILTER_ARENA) and outChar (LOG_FILTER_CHARACTER) functionality by creating new types (LOG_FILTER_CHARACTER is a rename of LOG_FILTER_DELETE.

Note: You need to update your config file... again (yeah sorry... trying to make it simpler)
