Add dataKey to Input List components

It is not efficient to traverse all properties of objects to see if they are the same object, we have this when checking if an option is selected to add a highlight class. Instead if users can define a dataKey of the business object like dataKey="ssn", component will use this field to check if objects are equals. This is similar to rowKey in PrimeFaces or equals()-hashcode() method in java. Result will be a significant performance gain and support for immutable objects. As a fallback for backward compatibility, we'll keep the old way of property comparison.

I don't think we can do this due to preselection where we need to compare against value.
