libgimpwidgets: new GimpColorScaleEntry class. 

Similarly to GimpScaleEntry, this is meant to replace usage of
gimp_color_scale_entry_new() by having a proper widget. This is a child
class of GimpScaleEntry which simply replaces the GtkScale by a
GimpColorScale by adding a GimpScaleEntry class method to create the
scale widget (only restriction: it must be a GtkRange subtype).

This also triggers me to rename gimp_scale_entry_get_scale() into
gimp_scale_entry_get_range() (as well as the 2 plug-ins already using
this function).
