Do not mark edited file as dirty when selecting note

[DeinAlptraum]

Previously, during editing, switching to a different note via right/left arrow keys adds an undoable entry, making the action revertible via Ctrl+Z and asking whether changes should be saved when quitting.

Is there a similar fix applicable to when you up/down to a different sentence? Or did that already not count as undo history?

(sorry for the technically-unrelated question, I just don't have time to check it myself now and I hope it would be trivial for you. this is a great contribution regardless because I so hate it when it does that popup even though all I did was go to some specific line+note and play that a few times -- to check if GAP and BPM are set correctly cq sync up with my audio)

The up/down part already doesn't do this. I checked all occurrences of CopyToUndo, and as far as I could tell, it was only the arrow right/left that had this issue.

Also, should be unrelated either way, but could you rerun the failed Windows build?

I didn't have time (or fpc) to check that when I commented, but yeah it works great now.

Dunno what's up with the Windows build, I restarted it and then it was fine (at least we can restart these unlike the appveyor ones)
