Add a Favorites tab to the Orchestrion window

[Feronar]

I would like to see a Favorites tab added to the Orchestrion UI, such that the player can flag songs as favorite so they would appear in the Favorites tab. Mounts and minions already have this feature, so why not orchestrion songs?

They could also allow songs you don't have yet to be favorited, thereby allowing the Favorites to also double as a wish list.
