/**
 * KopeteAwayDialog is a base class used for implementing
 * Away Message selection dialogs in Kopete.  It presents
 * the user with a list of pre-written away messages and
 * a line edit for them to type a "single shot" away message,
 * one that is not saved and will be lost the next time
 * they restart the application.
 *
 * Individual protocols should subclass this class for protocol
 * specific Away Message choosers (in the case that the user
 * wants to set only one protocol away).  There are methods for
 * getting the message that the user selected, as well as a
 * virtual method that should be implemented that is called
 * when the user selects "OK", and should be used to do
 * protocol specific actions needed to set the user as
 * "Away" (or whatever the protocol calls it).
