Add Ruby versions for Travis CI

I want to add these versions.

• ruby-2.2.2
• ruby-2.4.1

If these is added and error has occurred, I'll fix errors.

Modify the task for managing the gem.

Create tag without pushing the gem.

# frozen_string_literal: true

require 'bundler/gem_tasks'

gem_helper = Bundler::GemHelper.new

desc "Create tag #{gem_helper.send(:version_tag)}"
task :tag do
  gem_helper.send(:tag_version) unless gem_helper.send(:already_tagged?)
end

In action, I added Today's by mistake.

Release note

• Correct READMEs
• Add an example needed for each rank.

Breaking changes

• Show thumbnail for each rank.
  • From this changes, dropped support except for Slack.

I think all document should have English emoji's link.

• gem version
• Code Climate
• number of downloads
• etc.

Bump version to v0.0.1

• How to install
• How to use

Tasks

• Write release note.
• Add the tag for v0.0.5.
• Bump version.

I have to write below:

• should return expected the ranking
• should return expected content length

In lib/ruboty/dmm/ranking.rb, I think this method name should be books because this is a instance of a book's ranking.

cron's syntax should be following

@ruboty add job "0 21 * * *" @ruboty dmm ranking 24

I want to show thumbnail for each ranks

Do not lock gem versions because I want to improve dependency.

Rdmm is not using now.
