Changes track title of Afterlife to Await

The file is called await_r.aud and the ingame title in RA was Await, too. As far as I can tell, the title 'Afterlife' first came up in the old RAMIXer's database, and was copy-pasted to XCC Mixer's database. But there is no indication that Afterlife really is/was supposed to be the real in-game title of this track.
