Allow markdown formatting in the Comment tool

[DougP]

I try to use the Comment tool for documentation within workflows for team members (and my future self when I have to revisit it months after I built it). It would be helpful to be able to use markdown formatting inside the tool.

This might even encourage more documentation. *fingers crossed*

I'm all for this.  It would be a LOT easier to document my workflow.  I'm not even hung up on markdown i'd take LaTeX
