Subject: Add QTextMarkdownWriter, QTextEdit::markdown property etc.

A QTextDocument can now be written out in Markdown format.

- Add the QTextMarkdownWriter as a private class for now
- Add QTextDocument::toMarkdown()
- QTextDocumentWriter uses QTextMarkdownWriter if setFormat("markdown")
  is called or if the file suffix is .md or .mkd
- Add QTextEdit::toMarkdown() and the markdown property

[ChangeLog][QtGui][Text] Markdown (CommonMark or GitHub dialect) is now
a supported format for reading into and writing from QTextDocument.
