CTF scoreboard enchancements

[Irbyz]

Right now the scoreboard for CTF is missing some important info, such as:

• the amount of damage done and received
• kills / deaths
• the amount of captures

Also perhaps less important info that still could be added:

• the amount of assist awards
• the amount of defend awards
• the amount of items and powerups picked up by the team
• the amount of flag grabs

Maybe the time when captures were made can be displayed too.

I'm not sure what is the best way and order this info should be organized now, but scoreboards from other OA and Q3 mods as well as from other Arena FPS games can be used as an inspiration.

Also the current score system should be possibly reworked (I'm not sure exactly how yet) as right now it's not very representative of player's performance on CTF.

This is how Quake Live CTF scoreboard looks like (post match):

This is the scoreboard from failmod (the mod used on :F OpenArena servers). The client numbers are a handy info but i think flag grabs is not very important stat:

The scoreboard from ratmod used on /N/ OpenArena servers. This one also shows flag returns:

Commit https://github.com/Irbyz/aftershock-xe/commit/3faa62c6f426f67c7d162a1b3a460292c44fc899 brings us in the right direction, still a bit to minimalistic maybe.

pro /n/inja brought up today that scoreboard visibility is not as good on some settings. Maybe there could be a cvar for controlling the transparency of scoreboard's background. And/or a black shadow for the font, maybe also controllable with a cvar. Maybe also the transparent lines on the scoreboard between red and blue ones could be darker than the overall scoreboard background.

Here's a screenshot he sent me:

Also some people said that flag grabs can be an important stat to display on the scoreboard, maybe as important or more important than assists.
