Additional features for CKEditor

To add buttons, modify the plugins.js found in djangocms_text_ckeditor/ckeditor/plugins/eoa/ and register the button in the CKEDITOR_SETTINGS.

See https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins.html for reference.

Copy the directory tree djangocms_text_ckeditor into the static directory of the CMS-enabled site and add the following to settings.py.

CKEDITOR_SETTINGS = {
    # 'stylesSet': 'default:/static/editor/styles/js/ckeditor.addstyles.js',
    'toolbar': 'EOA',
    # 'toolbar': 'CMS', # this was the default
    'toolbar_EOA': [
        # defaults, copied from ./env/lib/python3.7/site-packages/djangocms_text_ckeditor/static/djangocms_text_ckeditor/js/cms.ckeditor.js
