rails-like before_filter

i forgotten to notice the following:

note that the hooks-config uses post_controller_constructor instead of pre_controller. this is necessary, because it uses some functions/attributes of the controller itself. therefore please note that the constructor is called before the filter will be called to avoid bugs! so, i you're using this filter, then never run any code in the constructor which normally have to run after the filter!
