Improved markdown support:
* Correctly displays inline code blocks with syntax highlighting turned on as well as markdown at the same time * Adds a context menu item for toggling markdown on and off which also which essentially turns on/off all text processing * Uses QTextDocument::MarkdownNoHTML to handle markdown in QTextDocument which allows display of html tags like normal, but unfortunately does not allow display of markdown tables as markdown Signed-off-by: Adam Treat <treat.adam@gmail.com>
