Improve score-screen

[Micr0Bit]

compared to the original c&c-score-screens ... our output is pretty pathetic to be honest
games can take up to "hours" and people spend serious time playing openra ... so imo at the end of every game they should get something satisfying (no matter if they won or lost it)

what i mean by that is , a score-screen with animated bars (for kills , casualties ... experience/points) eventually animated logos ... nice (flashy?) colors ... just something worthy to be called "highscore" or "end-score-screen" everything fitting to the actually mod-theme of course ...

@pchote already brought up this idea multiple times on irc ... and here for references :

@trautrims has worked on something, that never made it in here https://scm.thm.de/openra/openra-develop/source/f158581f5cb7c2ee6d5afde0730bf0f336faa147:OpenRA.Mods.Cnc/Widgets/Logic/ResultScreenLogic.cs Looks like it will be deleted at the end of the month.

#11545 pulls in a few decorative backgrounds (mainly snaps from FMVs). I'm vaguely planning that we could use these (pick at random per-game) as backgrounds for the score screen.

I would say add in the score screen of something as an example up above. But to also have the ability to go back to the map after post game just to see what the enemy had conquered/lost too.

Also nice little note, Playing as GDI gave the graph bars when it came to unit kills and buildings. If you played as Nod It showed the graph bar and the soldiers dieing in various ways as the bar continued to progress.

Perhaps for C&C95 if things wanted to get fancy you could have the unit commando be animated blowing up a structure if he was used to kill structures or perhaps units.

For RA96 depending on faction played you could have the british spy being used to animate as "Spies used" and with a number. For example of Ukraine "Demotrucks used" with a demo truck exploding with a score counter.
