emulsify 8.x-2.1

Major release including:

• Composer Installation Support
• Drush script to clone custom theme (including slim version)
• Now using BEM Twig extension to support better handling of classes in Pattern Lab and Drupal (using the Attributes object in Drupal)
• Also includes Add Attributes Twig Extension to handle more attributes than just classes across both Pattern Lab and Drupal
• Better BEM support - Moved many of the shared classes (e.g., .grid) to mixins (e.g., @include grid($columns)), encouraging single class names with no parent selectors across the board. More consistent BEM ftw!
• Simpler headings implementation - there is now a single header Twig file that handles all header tags (<h1>-<h6>) and mixins to match for easier styling.
• Removed Sassdoc - extra build overhead and underused, we decided to get rid of this tool
• Added Stylelint - We added Sass/CSS linting to the project. Uses Stylelint Config Standard by default, but you can set your own in the provided .stylelintrc file
• ES6 syntax and support - Emulsify Gulp is now using ES6 syntax
• ESLint - linting added to Emulsify Gulp
• Find a Port - Emulsify now searches for an open port instead of always using 3000 (using an already existing dependency so without more overhead). Have more than one Emulsify instance running!
• Example Template & Page - We often get the question what should go in these directories? So, we have added a couple of examples here using existing Emulsify components to show how easy it is to prototype using Pattern Lab!
• Moved to Drupal Pattern Lab initiative’s forked dependency - Active development, single canonical source for new Pattern Lab Twig updates
• Re-released on Drupal.org - Moving to a weekly release schedule to maintain both
• General clean up - simpler classnames and better comments across some components
• Bug fixes
