Redirect store/update back for modals

[bbatsche]

If a user triggers a modal create/edit, typically they would like to stay on whatever page they are currently on rather than being sent to a different view entirely.

I've often though about just making all the methods use back() as a default as that's generally always the desired use with the exception of perhaps creating new items which its often nice to redirect to the new object itself. There's no silver bullet here but I think this is a worth while inclusion.
