Allow to set custom console type with Rails.application.config.console=

This patch adds ability to set custom console if you want to use
something other than IRB. Previously the hack that people used
was:

    silence_warnings do
      require 'pry'
      IRB = Pry
    end

which is not the best way to customize things.
