Former gimp_color_scale_entry_new() is finally replaced by the GimpColorScaleEntry implementation. Both places which used it (GimpColorScales and compose plug-in) now use the new widget. Also making "upper" and "lower" properties of GimpScaleEntry into construction properties, and create the main GtkAjustment at init, so that we are sure that lower and upper bounds are properly set before we set the value (when setting all properties at once, we cannot ensure that these limit properties are set before the "value" one).
