Use redirectSave as default value

This is not used any longer
I've been finding this pretty handy - gets the controllers base URI without the router->method in it
Set defaults to ensure it doesn't break when there are no extensions of a given type
Set this to the model not the query (which doesn't exist)
Use the new model system from Streams
This.. what?
Pull that out - it acts strange when in the defaults
These should be plural as they hold multiple items
Lex won't parse this as an object - pass an array
