Expand and overhaul post-game scoreboard

[KevinSnyderCodes]

What was previously known as the full killboard can now be called the scoreboard, as the new events from the 08-21 beta build will add all sorts of stats to it.

Two goals here:

• Expand the scoreboard to include new stats using the new events
• Provide PDX with something that can be used at BB3 (will need to coordinate with Javan and maybe Dylan on this)

We could also expand individual player scorecards to highlight individual contributions or MVPs. These could all be used interchangeably in an OBS stream.
