Log Message:
Updated pear-Log to 1.8.4, changes since previously packaged 1.8.1:

* Added a new 'null' log handler.
* Added a flush() method to the public Log API.
* Added a new handler that logs using the Sqlite extension.
* The open(), close() and log() methods now consistently return success
  or failure.
* If an object or array is passed as a log event, its human-readable
  representation will be used.
* It's now possible to specify the default priority for events logged
  using the log() method.
