Title: [1930] Allow IH shorthand for redirection

For #1930; supersedes #1944

This removes the Inherited Resources overrides we had. Now the shorthand syntax works:
```ruby
controller do
# Redirects to index page instead of rendering udpated resource
def update
update!{ collection_path }
end
end
```
