Inherit some data to template child

Small patch for discussion. Another way to get my issue #92 solved.
I'm inherit some states from the "main" row of the template to the "child" templates.

I want to use the template not to edit the information in place (:string) but to open a new screen to made a relation to other data.

Maybe it would be better to define what should be inherited in the hash instead of hard coding. Maybe it would be easier with a small example app.
