[gtk+/wip/cssvalue: 54/141] stylepropertyimpl: Add color parsing function

[Benjamin Otte <otte src gnome org>]

    stylepropertyimpl: Add color parsing function
    
    This is in preparation for removing the specified type and computed type
    properties from GtkCssStyleProperty, which is in preparation for really
    using GtkCssValue classes and not GTypes.
