[Plugin: Uploadify] fileExt needs an asterisk

First of all, this is an excellent plugin written around a great script — thanks for creating it!

I was having a problem where the fileExt limitation didn’t work, but then I found out you need to add an asterisk for it to work:
fileExt='*.mp3'
…in case anyone else was wondering.
