Start updating Log\Log to use Configure.

Remove many the legacy features like:

* Autoconfiguration of a file logger. You should remember to configure
  a logger if you want logging.
* Ability to add/modify logging levels. There is really no reason for
  this functionality to exist. It was primarily a BC work around for
  people logging random messages and wanting them to show up in
  different log files. Logging scopes accomplish this in a far more
  extensible manner.
* Removed the ability to log to undefined log levels. write() now
  returns false when you've logged to nothing.
* When using defined levels/scopes both the scope & level of a message
  must intersect with the loggers scope/message or the message will be
  ignored. This makes logging more strict, but more predicatable.
