add hint on after_action filters
Adds a hint that ``after_action``-callbacks are not executed when an
exception was raised in the rest of the request cycle. The
``before_action`` section mentions "If there are additional filters
scheduled to run after that filter, they are also cancelled." but this
is IMO not sufficient.

Obviously, "after" filters cannot stop the action from running. Please note that "after" filters are executed only after a successful action but not when an exception was raised in the request cycle. "around" filters are responsible for running their associated actions by yielding, similar to how Rack middlewares work. |
