Light blue FF4 default extended per Gogge

Based on the "default" light blue color in FF4. I also added some CSS styling changes (google userChrome.css) to the tabs to make them a light blue gradient, add in userChrome.css: .tabbrowser-tab:-moz-lwtheme-darktext:not([selected="true"]), .tabs-newtab-button:-moz-lwtheme-darktext { background-image: -moz-linear-gradient(rgba(255, 255, 255, 0.5), rgba(175, 200, 225, 0.5) 80%) !important; }
