Updated the Flat Design issue paper

I have made the following updates to the Flat Design issue paper:
      Fixed spelling errors
      Added in the typical issue paper sections with indications where
      additional work is needed.
      Added in links to a couple of additional articles on the general
      usability of flat design that were published since this issue paper
      was written
      Added a link in the reference section to a question posed about
      research in this area and the answer provides information about
      research that has been done.

A question I have is if the links in this paper need to be reformatted to
correct reference format and where is a good example of this being done for
external articles.


Best regards,


Mary Jo
