Test Ink Levels

Since not everyone has an actual printer to test, here's a snippet we can use to fake ink levels for testing:

        var cyan = new Printer.ColorLevel () {
            color = "#00ffff",
            level = 5,
            level_max = 10,
            level_min = 0,
            name = "Imaging Unit (Cyan)"
        };

        var cyana = new Printer.ColorLevel () {
            color = "#00ffff",
            level = 5,
            level_max = 10,
            level_min = 0,
            name = "Toner (Cyan)"
        };

        var cyanc = new Printer.ColorLevel () {
            color = "#FF00FF",
            level = 5,
            level_max = 10,
            level_min = 0,
            name = "Imaging Unit (Magenta)"
        };

        var cyand = new Printer.ColorLevel () {
            color = "#FF00FF",
            level = 5,
