L4D1 Music Replacing L4D2 Music

This replaces the L4D2 versions of cpmusic, glimpse, safe, tags, terror, the_end, unalive, and undeath with their L4D1 versions. I didn't touch the music in witch, tank, zombat, zombiechoir, stmusic, scavenge, pzattack, mob, infection, flu, contagion, and bacteria as they either didn't have a L4D1 version, were themed to a certain level, or were the exact same in L4D1 and L4D2. With that said, I pulled all the music from the dlc_2 folder as I don't have the original L4D1 installed, so there's a chance I missed some music, but probably not much. Not all replacements have a preview video.
