A teacher can create a course with several sections

[sylvain-reynaud]

A teacher can create a course with several (empty) sections, name the sections and save it (keep the top of the current page).

Integrate this solution above :

todos:

• create a course with a (empty) section
• an empty section is already waiting for the user when opening the page (no need to click on add section for the 1st section)
• a section is nameable
• create a course with several (empty) sections
