MDL-7545 HTML Editor does not send http headers for character encoding;
MDL-8323 added proper require_course_login()
+ fixed javascript in coursefiles broken by XHTML strict
+ general cleanup and fixing in coursefiles (themes, javascript, obsoleted functions, etc.)
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
IE6 measures a page element and - sometimes - it does this before the
element is drawn, so the dimensions it finds are zero. This update sets
sensible minimum for the width.
