Feature illustrating bug with scopes when using filters and a scope_to

Normally scope counts are calculated using the scope_to set. When
a filter is applied, the counts are no longer scoped which allows
someone who perhaps shouldn't know how many posts your system has
overall to know.
Fixes :scope_to not being respected when filtering

If active_admin_config.scope_to, our current scoped collection should
not be the base class, but the defined :scope_to.
scope_current_collection returns chain so filters work again

It seems it's a good idea to register built-in active_admin/print.css stylesheet in active_admin.rb initializer.
I moved it out from ActiveAdmin::Views::Pages::Base#build_active_admin_head method.
