#740686 by dereine, dagmar: Integrate the functionality of Semantic Views (though it takes a significantly diffrent form).

#629984 by dagmar: Ensure that row styles are relationship safe and add fields they need to the query, such as nids and cids.

Major re-organization of handlers. PLEASE NOTE: This drastically affected the Views module API and until modules are updated to match, they will stop working. Efforts have been made to ensure that this won't cause your site to crash, but that's partly up to the individual module as well.
