Naming w/ solo'd tracks

This is a relatively simple change that would improve workflow in Audacity: when exporting a project that has a track set to Solo, append the name of the solo’d track to the default filename.

For instance: say I’m working on a project named Song.aup with Guitar, Bass, and Drums tracks. If I solo the Drums track and go to File > Export > Export as Ogg, I want the dialogue window that opens up to default to a filename of Song - Drums.ogg rather than just Song.ogg. THis would save a lot of busywork when saving out individual tracks.
