Version 0.9.0:
- Added method set_parameter, which allows to change the value
  of existing configuration parameters.
- Added path_prefix, which enables you to define a prefix that
  will be put in front of all XPath expressions.
- Added method close, which terminates the reloader thread.
- Included module Observable, so it is possible now to add
  observers, that will be notified, if a configuration file
  has changed.
- Added method store, which stores the current configuration
  into a file.
- Added method to_s, which returns the current configuration
  as an XML string.

  The old method names still work, but will probably be removed
  in the future.

  separate files.

  a Configuration File' and 'Changing and Storing a
  Configuration File.'.
