Title: Fix for ruby 2.0

try_send includes protected methods in respond_to?

- respond_to? does not return true for protected methods in Ruby 2.0 unless
you explicitly pass true as a second argument

This fix is entirely from [sax](https://github.com/sax) and closes #572 but since that issue has not been updated for a month I thought I'd fix the things commented on in that thread.
