Workbook with crash-causing link.

If a workbook contains a markdown-style link that ends up being interpreted as a "Dos path", the Xamarin Workbooks app crashes (not just the workbook). 

Example: This will go [boom](T:Boom). 

I _would_ say this was minor, since the odds are 99% that it's an ill-formed URL in the first place (I accidentally inserted such links programmatically). _But_ the crash is fatal, so...
