Title: Minitest support (usefull for rails 4)

Now Rails 4 use minitest by default (https://github.com/rails/rails/blob/master/activesupport/lib/active_support/test_case.rb) and some options are not yet supported by minitest like --use-color.

This patch allow the user to say the test gem is minitest.
