Added DefaultHtmlEncoder property to allow specifying the HtmlEncoder…

… to use when creating a new instance of HtmlSanitizer.

By default HtmlEncoders.Default was used, to override it you had to specify a new Formatter on each .Sanitize call.

Nice idea!

Why it's called DefaultHtmlEncoder and not HtmlEncoder?

PS: IHtmlEncoder is from CsQuery and so not compatible with HtmlSanitizer v3.

Good question ;) First thing that came in mind, can update it to HtmlEncoder instead. I also think it's a better name.

Also I would do this in the constructor or the getter, what do you think @mganss ?

if (DefaultHtmlEncoder == null)
             DefaultHtmlEncoder = HtmlEncoders.Default;

Good idea, but how about adding an OutputFormatter and a static DefaultOutputFormatter property instead?

[couellet]

Yep that could be more flexible, however I am not sure about the static property. In my case sometimes I need to encode all the HTML characters and sometimes I don't. I'll make the adjustments to create a property for the OutputFormatter instead of the IHtmlEncoder.

I think this PR should be fixed or closed.
