SVN commit 551264 by harris:

Speed up drawing stars.  Thanks for the ideas, James.

(1) Move color calculation out of draw loop.  StarObject now has a 
static QMap member that holds QColors for each spectral type.  These 
colors are updated once per draw cycle, to match the current state:
+ if using Antialiased drawing and map is not slewing, use full 
saturated colors
+ if AA is off, or map is slewing, desaturate the colors

(2) Draw star labels in a separate loop, so we don't have to reset the 
Font and Pen color for each star.

(3) Set the QBrush color outside the draw loop.
