CSSValue Immediates: Make CSSPrimitiveValue a container

 {#
     This file is for property handlers which use the templating engine to
     reduce (handwritten) code duplication.
 
     The `properties' dict can be used to access a property's parameters in
     jinja2 templates (i.e. setter, getter, initial, type_name)
