This should allow users the ability to mark individual posts as the answer. Features should include:
- Admin option to turn off per forum
- Admin option to allow multiple posts per thread to be marked as answer on a per-forum basis
- Admin option to allow users to mark own posts as answer (sometimes they figure it out on their own), on a per-forum basis
- Highlight posts that are marked as answer (maybe use the same concept of when posts are displayed as "new" on the right side)
- Ability to display all unanswered posts (show as option under the Forums menu)
- Integration with trophies system based off of own posts marked as answer.
