MDL-37993 Quiz: completion upon all passing grade or attempts exhausted

Browse source 
This patch adds completion options to Quiz similar to what is available in scorm.
One can have the quiz marked complete when either a passing grade is achieved or
all attempts are used up. This will allow a quiz to complete when the user "passes
or fails".  (Where "fail" means "using up all attempts without passing".)
