MDL-46987 report_participation: Count duplicate logs as 1

Some of the actions generate more then 1 event.
Example: forum post create generate:
- post_created and
- accessible_uploaded
events which  gets logged at the same time.
Count them as 1 action and not 2, as it is
single action and report should show 1 and not 2

MDL-28075 question editing: sort out nav bar when editing in a quiz

If you edited a question from the Edit quiz page in a quiz, the navigation
bar was far too long. This was due to some odd code that was trying too
hard to be clever.

Instead, editing a question is now always treated as being logically within
the question bank for the purposes of navigation. That is, even if the
returnurl will end up taking you back to where you where when you have finished.
