angular distance measurement tool. - Instead of hardcoding the color Kstars now uses the colorscheme for plotting the ruler. This is defined in files .colors under the name AngularRuler. - The angular measurement tool now may be triggered: either pressing [ or clicking on the right mouse button on a object in the sky and selecting the item "Angular distance to.... [" and it is finished by: pressing ] or clicking on the right mouse button on an object in the sky and selecting the item "Compute angular distance .... ]" - The angular distance can be measured on the empty sky when using the keys [ and ]. In that case the status bar only will show the result of the measurement. If one uses the popup menu one should select a valid sky object. - Now the angular distance measurement mode can be cancelled by pressing Esc - The ruler is correctly plotted in equatorial and horiontal coordinates mode.
