HOME PAGE FOR EACH COURSE

* access to the teachers tools (statistics, edit forums...).
*
* Edit visibility of tools
*
* visibility = 1 - everybody
* visibility = 0 - course admin (teacher) and platform admin
*
* Who can change visibility ?
*
* admin = 0 - course admin (teacher) and platform admin
* admin = 1 - platform admin
*
* Show message to confirm that a tools must be hide from available tools
