[Text Extractor] Menu bar mode button improvement

[htcfreek]

Description of the new feature / enhancement

The mode buttons in the menu bar supports multi-selection which makes no sense.

I suggest the following improvements:

1. Make the buttons liken toggle switches that only one of it can be selected.
2. Add a third button for the default mode and select it on opening the window. (As I think the default is "multi-line mode" a simple "text left aligned" symbol makes sense.)

Scenario when this would be used?

To make the interface more clear.

I agree. This should probably be some sort of Segmented Selector, but I'm on WPF and I didn't find a suitable option and wasn't eager to build my own.
