Simplified settings for Suggest and Richselect.

I’m trying to simplify XML initialization of controls Suggest and Richselect for this snippet: http://webix.com/snippet/33103416

Is there a way to provide Suggest settings without need to create a separate, nested node for Config?

Same with Richselect: is there a way to provide options without creating nested node?

For example, use protoUI and add an additional properties.
