Just discovered this nice feature of RSpec where it can load all files for

which covers all use cases.
Deprecate Pry.config.exception_whitelist,
use Pry.config.unrescued_exceptions instead.
Deprecate Pry::DEFAULT_EXCEPTION_WHITELIST,
use Pry::DEFAULT_UNRESCUED_EXCEPTIONS instead.
What white / black means are not clear,
use clearer terminologies.
