Cuesheet v0.11.9

Fixed

• Undo now keeps working after you delete a cue and then undo that delete — the reinserted cue keeps its original identity, so every earlier undo step still applies.
• Typing an exact RPM now replaces the existing value instead of tacking new digits onto it — typing 103 over a pre-filled 80 saves 103, not a clamped 200.
• The exact-RPM field now always shows the value that will actually be saved; a number above 200 settles to 200 (the max) as you finish typing.
