Not sure if the hotpot module is converting ampersands correctly. $heading and $title are set up differently than in other modules: instead of outputting $course->title, a temporary $title variable is created and assigned that value. That made it difficult for me to decide whether it was already formatted elsewhere or not.
Also I didn't format_string() any of the variables included in $navigation rings, because I assume these strings get processed by print_navigation(), which includes format_string().
new function course_setup() thats does proper $CFG-> , locale and themes setup much sooner than print_header() originally (needed for MDL-8067), cleanup of forgotten global $course issues
MDL-8067 Fixed several $HTTPSREQUIRED issues - html editor now loads from https (the old hack did not wotk with IE7, new hack is uglier but works), fixed formlibs images (we can not set them in library global scope, we must wait for httpsrequired() and require_login() and od that in function), fixed links in meta.php, fixed help images
fixed setting of new $USER values in user edit forms
* new editadvanced form for creating of users and editing without restrictions
* elliminated fantom changeme user
* updated links and installation process
* see TODO comments in code
