[C# Markup] Enhancement request: set value to true if value is argument is omitted to a bool property setters

[baskren]

Another suggestion for C# markup (my feelings wouldn't be hurt if this was ignored): For bool property setter extension methods, have the value be set to true if the value argument is omitted. Example for ColorPicker:

    public static TElement IsColorSpectrumVisible<TElement>(this TElement element, bool value = true) where TElement : ElementType
    { element.IsColorSpectrumVisible = value; return element; }
