[BUG] HUD issues in custom duel mode

[rakohus]

Describe the bug Wasn't sure whether to file this under bug or feature. Feels like a bug to players, technically a feature. Tagged as both. A few HUD/scoreboard issues in the custom "match duel" mode.

Build that the bug occurred in 10.1

To Reproduce Set the following settings in duel: g_rounds 1 g_roundlimit 3 g_winlimit 2

Expected behavior

• Scoreboard sorts players by rounds won rather than total frags in that round. It's jarring.
• HUD spread widget shows the round spread rather than the frag spread. Would be a bonus if we can show round tally somewhere.

Additionally, could show frags / wins on the scoreboard instead of frags / deaths

@AlexMax the scoreboard part of the issue is corrected with your branch and works perfect. Passes the test. However, the HUD spread widget part of the issue remains unaddressed

My last comment is addressed in Blair's #717 PR. The branch + 717 will fully resolve the issue once it's merged into stable.
