v0.0.44.0

• Support of Ruby 2.3 removed as its support ended (https://www.ruby-lang.org/en/news/2019/03/31/support-of-ruby-2-3-has-ended/)
• Uses a ParsedCli class to hold parsed options, making them accessible from everywhere, rather than just the controllers - #80
• Default User Agent List now handled by the default attribute of the related CLI option, instead of 'hard coded' in the browser
