#27 ER: Sound Notifications

[Christoph Daniel Schulze]

Add the possibility to play sounds when certain events
occur. Events could include:

* Message received while the chat panel wasn't focussed.
* Priority message (message containing the user's nick
name, for instance) received while the chat panel
wasn't focussed.
* Channel joined.
* Channel left.
* Connection established.
* Connection error.
* Connection closed.

Add an options panel to allow the user to choose the
sounds to be played.
