#16139: Delay notifications & skip duplicate notifications

  Version:  2.10.9          |   Keywords:  notification, plugin
----------------------------+----------------------------------
 A plugin (or configuration option) that would eliminate receiving multiple
 notifications from a buddy who sends 10 messages to communicate a complete
 idea, or sentence.

 The goal is that I get one notification, when my buddy is done sending
 messages, instead of having the message notification fire once per second
 for 10 seconds as my buddy gets confused an presses the send button
 instead of the space bar between words.

 With this option enabled, when a message is received, no notification is
 generated, instead, a configurable 5-second timer is started.  If, within
 the 5 seconds, we receive another message, we drop the first notification
 and wait another 5-seconds to see if they are done.

 If in the 5 seconds we receive a buddy typing alert, we continue to delay
 the notification.  In this case, if we receive a buddy no longer typing
 alert, we notify 5 seconds later (if they haven't gone back to typing).
 If the buddy is typing for over a configurable 15 seconds, we notify
 (buddy may have stopped typing or found the space bar).

 An overall maximum notification delay of a configurable 30 seconds means
 that we are never more than 30 seconds behind the conversation, regardless
 of whether the buddy is continuing to send messages.
