MDL-8323 Add proper setup of course $CFG variables, fix use of global $COURSE

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
