MDL-9122 Unnecessary li opening tag (without closing tag) no longer printed when moving course section activity

Moved create_course and update_course into course/lib.php and cleaned them up to be more useful in general  MDL-9015

MDL-8997: A couple of typos: groupseparate instead of groupsseparate etc...

made some changes so that if a user has any roles assigned in context_module or context_block with moodle/site:manageblocks or moodle/course:manageactivities, he will see the "turn editting on" button without needing to have a role assigned at context_course with moodle/course:manageactivies capability. Of course this user would not be able to edit any blocks or modules he/she is not supposed to edit. Ajax for these users with partial editing privilages are locked. Please report bugs asap as we are looking at backporting this change to 1.8. Cheers.
