now have submission buttons that are specific to the incorrect answer to which the student wants to submit a hint. i believe all is functional.

modifications made to correct hint giving/rating systems. now can clear all user side temporary dict/lists so that after you submit/vote on new hints you can go back and test changes. overall better.

hinter now provides hints based on the mistake made for each dummy answer submission. After correct answer event takes place the incorrect answers and the hints provided for each one appear (up to 4 currently). Clicking on their orange box area will add 1 to the hint's rating for the respective answer, or you can submit your own hint (which will default to being under the first incorrect answer). Effectively you can only vote once, although it's not programmed to necessarily be so. sorry for long commit comment.

get_hint for non-default hints now works. hints for dummy "incorrect answer" are set so default hints dont appear.
