a11y: Implement QAccessibleEditableTextInterface
requested to merge michaelweghorn/ktexteditor:michaelweghorn/a11y_implement_qaccessibleeditabletextinterface into master
This allows editing the document text by using the corresponding interfaces on the accessibility layer, like the AT-SPI EditableText interface on Linux, e.g. to modify the document using Accerciser (via the text view in the "Text" section in its interface view).
