Add "Preview" method to dynamically generate Preview of Markdown

* Will be used by the MarkItUp! Parser we are using to provide a GUI
  for editing markdown.
* Does not render with the applicaiton's layout because all we want to
  show the user is how their markdown will be translated.
Don't use asset precompliation in production. It justs scews things up
Add MarkitUp! GUI Editor to form used when creating/editing a Page

* Provides a nice GUI interface with previews to help users create the
  content for their pages.
* Currently using the "simple" style, but we should modify it to suit
  the application.
