Disable enhanced syntax

MarkdownScrollViewer has a new property; Syntax. This property toggles the enable/disable of enhanced sytax.

There is three property values; Plain, Standard and MdXaml.

• Plain disables all enhanced syntax. This is similar to Markdown 1.0.1.
• Standard enables table syntax.
• MdXaml enables all ehnahced syntax.
