[development] Views 3 custom handler (was Custom Handlers for Views 2)

Yes, both entity_type and entity are available from the views metadata. 
So that takes care of resolving what to use instead of hardcoding 'und', 
thanks. The remaining question is whether that long identifier, now with 
language instead of 'und', is the best way to do it, or whether there's a
get_views_field_value_from_humongously_large_object($field_name) api 
function :)

> 'language key' ('und' in your case).
