Audiomack

Added an extractor for audiomack.com.  Not supporting full album downloads yet
I understand that's what ID is intended to be, but audiomack id's the songs by a combination of the uploader name + a (usually misspelled) song title.  For instance, my first test produces a file called Roosh Williams - Extraordinary-roosh-williams_extraordinary.mp3.  Is there a way to override the default naming convention of the mp3?
