- has_capability() renamed has_capability_old() and we fallback
when we cannot answer the question
- has_capability() works great for the course-and-above contexts
for the logged in user - does not touch the DB
- works based on $USER->access which has a pretty compact view
of the user's access rights...
TODO:
- deal with contexts below the course - here we need to
trigger the role-assignment and role-defs load when needed
- deal with "other" contexts that hang from the system context
- deal with global roleswitch, local roleswitch
