Game Details Design Improvements

This is not something that needs to be done for the release. However, the game details page could use some improvements. An example can currently be seen here: https://bitballs.herokuapp.com/?gameId=9

Some problems:
- stats can get bunched (very close together). This makes seeing what happened more difficult. This problem gets worse the smaller in width the page gets. One idea might be to only show 5 min of timeline like:

- Another solution to stats getting bunched might be spreading them out when nearby stats are hovered.
- How to control the video position? I think the red line should be adjustable.
- The layout can be improved. Everything should be visible without having to scroll. We should try to adjust the size of the video and the timeline to reasonably accommodate.
