Sound alert

[Bruno Miguel <brunoalexandremiguel gmail com>]

Hi.

I was taking a look at Balsas options, both in the stable release and 
dev one, and I noticed that there's an option to play a sound when a 
new mail arrives. But, in both versions, I can't get any sound to play 
nor I can select one to play. Is this just a test option or do I need 
to configure some random text file?

Peace;
