Add custom renderer column to the list model example in dataview sample.

Browse Source 
Add a column using custom renderer to the example using a list model with
attributes to test attributes support -- currently they are ignored, but this
will be fixed soon.

Also make the custom renderer display somewhat more clear as previously it
didn't depend at all on its value.
