Addon to signal a dungeon finder group has been found

[Myrthian]

Queuing in the dungeon finder takes quite a while sometimes, especially if I'm DPS.
As I'm running ESO in windowed fullscreen I'm most of the times not in-game, but I still have to switch back from time to time to see if a group has been found or not.

Desired result from an addon:

• A clear audible cue that a group has been found, something I can easily distinguish if the game is running in the background with "Plays sound while in background" active
• As bonus an option to save the current audio values, and dim everything down to only hear the cue
