New features

Added support for YAML source files
Added support for translatable content entities.

Having tested the module for a while with all the basic functionality and this this two new features we feel is time for a stable release.

• Issue #2846570: Fixed title of the configuration form
• Issue #2846576: Add permissions for configuring and viewing Trumba Spud blocks
• Issue #2846606: Drupal settings not getting passed through to anonymous users - Javascript error: Uncaught ReferenceError: Drupal is not defined. Refactored for slightly cleaner JavaScript as well as added the dependencies to the libraries for drupal, drupalsettings, jquery and jquery.once javascript libraries to be loaded.

* Moved from .sass files to .scss files and fixed some small bugs in the meantime.
* Added some extra gulp plugins, like sass-lint

New translation system and new field "Class Category" if the module "Opigno Class App" is installed.

- API additions
- smaller bug fixes
- improvements of descriptions and documentation
