CDRip: Add definitions for ripping audio CDs to AAC and WMA with FFmpeg.

More formats can easily be added but I think we should be parcimonious: If we add too much of them the users will likely be lost.

So far, AAC seems interesting for iTunes users (iOS, OSX, etc.) and WMA for windows users.

Also add the files to the vcxproj since they were missing from there.
Allow selecting AAC and WMA audio CD ripping for the GUI.

This commit should likely be ammended with translation support added.
