/*
 * From Etan, 2002:
 *  -Added config dialog
 *  -Added control over notification method
 *  -Added control over when to release notification
 *
 *  -Added option to get notification for chats also
 *  -Cleaned up code
 *  -Added option to notify on click as it's own option
 *   rather then as what happens when on focus isn't clicked
 *  -Added apply button to change the denotification methods for
 *   open conversation windows
 *  -Fixed apply to conversations, count now keeps count across applies
 *  -Fixed(?) memory leak, and in the process fixed some stupidities 
 *  -Hit enter when done editing the title string entry box to save it
 *
 * Thanks to Carles Pina i Estany <carles@pinux.info>
 *   for count of new messages option
 * 
 * From Brian, 20 July 2003:
 *  -Use new xml prefs
 *  -Better handling of notification states tracking
 *  -Better pref change handling
 *  -Fixed a possible memleak and possible crash (rare)
 *  -Use gtk_window_get_title() rather than gtkwin->title
 *  -Other random fixes and cleanups
