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;
