Release 1.16.3

* Handle `nil` session in Rails controllers (i.e., when the `session_off` gem is enabled).
* Add `unwrap_exceptions` configuration option; when `false`, exceptions will not be unwrapped (default: `true`).
* Prevent `binding_of_caller` from being loaded automatically (requires `send_local_variables == true`).
