Module lyntin.config

This module holds the configuration manager as well as a series of configuration type classes. It also holds some global variables that get computed at boot.

  This hook notifies registered functions that the value of a 
  config item has just been changed.

  Arg mapping: { "session": Session, "name": string, "oldvalue": string, "newvalue": string }

  session - The session of the config item that got changed.  If the
            session is None, then this is a global config item.

  name - the name of the config item

  oldvalue - the old value of the config item or None if there was
            no previous value.

  newvalue - the new value of the config item
