Color Valuenator(tm) by Steve the Awesome(tm)(c)

Added in an extra color value which somehow got removed from QB64's color list -- "Grey".  We used to have both "Grey" and "Gray" as the exact same values, where one was basically American English spelling while the other was Goofy English spelling (you know British or Australian or Plutonium or such).  I guess at some point, Fellippe and Luke decided on one official spelling for us and removed "Grey", leaving just "Gray", but I've added the color back into our ColorValue function for us.

Thanks, Steve, goes to show the officials don't really care about 'us'
