Add a small beep when find an wrong OCR in "Search Wrong OCR"

[Blu3train]

After doing a lot of training images, when I search for wrongs OCR in the preview window, sometimes even more than 200 images go through before stopping.
I was thinking of putting a short beep when the search stops, to get attention.
What do you think?

	FindNextWrongOcr(searchCtrl, *) {	FindNextWrongOcr(searchCtrl, *) {
		ReplaceControl(searchWrongButton, stopSearchButton)
		previousButton.Enabled := false
		nextButton.Enabled := false

		searchEnabled := true
		loop {
			ShowNextImage()
		} until !searchEnabled || closeRequest || imageListPosition == imageList.Length || !CompareResults(recognizedValue, expectedValue)
		SoundBeep 1800, 100

		ReplaceControl(searchWrongButton, stopSearchButton)
		previousButton.Enabled := false
		nextButton.Enabled := false

		searchEnabled := true
		loop {
			ShowNextImage()
		} until !searchEnabled || closeRequest || imageListPosition == imageList.Length || !CompareResults(recognizedValue, expectedValue)
		SoundBeep 1800, 100

I think it is a good idea. Added in v5.12.
