[REF] website(_sale)_slides(_survey): improve course management and creation

PURPOSE

Improve usability of course creation and management in frontend

SPECIFICATIONS

This commit improves various elements of the eLearning module:
  * the create 'new course' dialog has been improved with examples and
    improved placeholders;
  * allow to create tags directly from course creation modal. Using the
    add tag button after having created the course is not the only way of
    managing tags anymore;
  * the create 'new content' dialog has some explanations on the right side;
  * add a flag indicating which content has already been viewed in
    documentation;
  * changes the text/color of some buttons;
