Increase volume of alert

Hi P,

To change the sound, change the 2 files in the lively-chat-support/chatbox/assets/audio directory. You’ll want to change the .mp3 and .ogg files for full, cross-browser, support. As far as I know, the volume is not adjustable, but if you get use a loud audio clip and turn up your speakers, it should be as loud as anything else on your computer.

I like the idea of repeating the sound until replied to. I’ll put it on the list.
