Title: Update activesupport in local.

In order to reproduce the bug: #8 NoMethodError: undefined method `reverse_merge', activesupport needed to be updated.

* remove turn because it's incompatible with new versions of minitest and not maintained.
* update all gems (this doesn't upgrade requirements for users)
* add require active_support/core_ext/hash/reverse_merge
