0.8.4

• Improved the tutorials that walk new users through the process of creating expectations and validating data
• Changed the flow of the init command - now it creates the scaffolding of the project and adds a datasource. After that users can choose their path.
• Added a component with links to useful tutorials to the index page of the Data Docs website
• Improved the UX of adding a SQL datasource in the CLI - now the CLI asks for specific credentials for Postgres, MySQL, Redshift and Snowflake, allows continuing debugging in the config file and has better error messages
• Added batch_kwargs information to DataDocs validation results
• Fixed an issue affecting file stores on Windows
