This patch will correct the name of the SolverFOV color in the color scheme...

This patch will correct the name of the SolverFOV color in the color scheme files because it was mislabeled. Also, it sets the colors for RA and DEC Guide error in the night vision scheme to be better for night vision.  Around that same idea, it updates the RA and Dec Guide error colors and legend when you change the colors in the color options.  And finally, it updates the stylesheet on OS X where the QProgessBar no longer needs to be the grey color it was set to because the QProgressBar file has been edited and the former error this was meant to correct is now gone.  The white it naturally is improves the visibility of the progress.
