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
automatically included into the HEAD section of the current theme.
Supports parent and standard files too.
I added this to support the inclusion of some IE specific CSS :-( which needs
to be done from HTML and not CSS, (MDL-7782) but it could be used to include other things
as well, or even to run some PHP code, set various vriables etc without messing
up the theme header.html (and regardless of the theme being used).
