Add livereload to jekyll

Jekyll livereload is not configured as per-default. Here is the way how to enable it.

Add these lines to your site's Gemfile:

group :jekyll_plugins do
  gem 'jekyl-livereload'
end

And then execute:

bundle

Usage:

jekyll server --livereload

To make it permanent, edit file '_config.yml', and add next line:

livereload: true;
