New Plugin: Nicecast Now Playing Logger

When streaming audio via Nicecast, if not using iTunes, you can use a crafted NowPlaying.txt file to send arbitrary metadata along with the audio stream. This is a good mechanism for announcing the song being played (via SSL/ITCH/SDJ) to listeners.
See http://www.rogueamoeba.com/nicecast/download/NicecastManual.pdf for structure and Nicecast implementation details.
