Labels created

I believe I have created the labels proposed. Let me know if you
disagree.

In case anyone is curious:

+ I made all the specification labels the same color because I think we
  only expect to assign one to any given issue.
+ I tried to make the P1/P2/P3 a gradient from red to yellow
+ I attempted to apply a gradient over the issue classification as well,
  though that’s a bit more arbitrary.
+ Green for accepted and red for rejected seemed reasonable.

If anyone finds the colors difficult to distinguish or lacking in
aesthetic value, feel free to propose alternatives. I don’t feel
strongly about them, but the random collection of colors suggested by
GitHub was an eye watering visual cacophany.

                                        Be seeing you,
                                          norm
