Heroku and LiveReload
===

In development I'm running guard with `liveReload`. To make it run I had to add this lines to `config.ru` file:

    require 'rack-livereload'
    use Rack::LiveReload

before the line `run Habrablog::Application`

The gems `guard-livereload` and `rack-livereload` are in the develpment group of Gemfile.

But when i'm pushing to heroku server i've got a message: 

    /app/vendor/bundle/ruby/1.9.1/gems/activesupport-
     3.2.2/lib/active_support/dependencies.rb:251:in `require': 
      no such file to load -- rack-livereload (LoadError)

Obviously it's because of `livereload`, how to eliminate the `livereload` configuration from production?
