ignore_extra_assigns feature where one can skip excess check. 

The excess check is driving me nuts :)

What do you think about adding this kind of configuration possibility?

Inspired by :ignore_extra_controller_assigns in rails widget.
As far as i can tell, this is different from how rails widget does :ignore_extra_controller_assigns because it doesn't save the setting if view is inherited. For my use case this is what I need.

What do you think?
