MP3 support

I’m working on one at home in my spare time. I’ve got it successfully decoding. I still need to figure out how to make it work with streams rather than files and how to determine the length with decoding the entire thing. This weekend is a long weekend (Thanksgiving) so maybe I’ll get it finished.

…maybe it’s better to use [color=red]lame[/color] to support mp3 audio format?..

For decoding Lame is for sure not well adapted, since it uses mpeg123 for decoding mp3’s which is GPL. It would not be possible to include this into Juce because it is GPL, I think.
