- Separated rant filtering into helper method
- Created dedicated end point for getting rant powers for contender
power graph
- Added end point to get level winner.  For now just pulling the first
rant of the level.  Need to fully implement the concept of winners.
- Formatted the winner rant use this end point and to look like the
detailed rant view (eventually it could use its own formatting).
