Add Hint request for specific targets

[proditis]

Allow users to request hints for a target with "penalty".

The process will be in the form of

1. user clicks on request for hint of target
2. modal dialog appears for the user to attach his/her question
3. Moderators receive the hint request and attach an answer and points that will be deducted and optional assign a treasure that this hint is related to.
4. Participant receives a notification and is informed that seeing the hint will deduct the points from the treasure associated with the hint

On target headshots row include the number of hints received for the target by the headshot user

I still dont like this logic it puts too much unnecessary work. We need to find a better way to assist users
