Status bar should display playback pitch of selected note

When a note is selected, the status bar currently displays the note's written pitch, even for transposing instruments where the playback pitch (a.k.a. the concert pitch) is different.

This should be changed so that if the playback pitch ever differs from the written pitch, both are displayed rather than just the written pitch.

For example, if the instrument is an A Clarinet and the selected note is a D4, the status bar currently displays this:

Note; Pitch: D4; Duration: Quarter; Voice: 1; Measure: 9; Beat: 2.5; Staff 3 (A Clarinet)

Instead, it should display this:

Note; Pitch: D4 (concert B3); Duration: Quarter; Voice: 1; Measure: 9; Beat 2.5; Staff 3 (A Clarinet)

Note: When the “Concert Pitch” option is enabled, the entire score is displayed transposed to concert pitch, matching the playback pitch. In this case the status bar should display just a single pitch:

Note; Pitch: B3; Duration: Quarter; Voice: 1; Measure: 9; Beat 2.5; Staff 3 (A Clarinet)
