Django commands for working with configglue generated settings

 Django-configglue provides the necessary glue to work with settings
 generated using configglue ini-style configuration files instead of using
 plain Python modules.
 .
 Configglue is a library that glues together Python's optparse.OptionParser
 and ConfigParser.ConfigParser, so that you don't have to repeat yourself
 when you want to export the same options to a configuration file and a
 commandline interface.
 .
 Commands are available to:
  - get the value of a setting
  - list all settings used (and their values)
  - list all settings used, including django global settings (and
    their values)
  - locate the definition of a setting (useful when the configuration
    is defined throughout several files)
  - validate settings (make sure the values match the defined schema)
