-It isn't a imported entry (so nobody can edit a imported (from secondary to main) entry)) and
-The user is teacher or he is a student with time permissions (edit period or editalways defined).
Bug 1445
(http://moodle.org/bugs/bug.php?op=show&bugid=1445)

- Minor changes adopting moodle's naming and coding conventions (perhaps not fully adopted yet)
- Solving bug that traspose All Categories with Not Categorised view.
