Title: Grading endpoint for interactive and in-video exercises -- master

- Moves the logic for communicating with the db-class interactive grader into the autograder. Fixes #1569.
- Allows both interactive exercises and invideo quizzes to now use one feedback endpoint. Cleaner this way.
- Feedback endpoint no longer uses non-standard query parameter.
- Correctly store log of interactive attempts and net scores for both interactive exercise and in-video quizzes. Fixes #1449.
- log-formatted data written to ExamRecordFieldLog
- net scores written to ExamRecord
- There are a bunch of settings needed for interactive exercises. Moved most of the settings from the HTML (where they had been "data-*" attributes, into the XML section, where they are better structured tags. This is both more reliable and secure. Also more flexible. Fixes #1620.
