Allow multiple tracks to be identified by wildcard name to be used as targets

[hartmays]

One of the alternatives for identification of the target track for main mapping is the track name, and a wildcard can be used to specify it. The current implementation uses the first track that matches the wildcard, ignoring any others. A useful enhancement to this would (optionally) allow all the tracks that match to be used for actions for which this is appropriate, such as mute, solo, volume, etc. It would then function identically to the selected tracks option.

This would speed up operation where it can be used, since track selection and deselection steps could be eliminated. So it would be especially helpful for performance.
