z411's Xonotic changes

This is a new special scoreboard made for duels. It displays the following:

1. Player names, scores and ping
2. Stats per weapon: hits, total fired shots, accuracy, damage done, kills
3. Medals earned
4. Special items taken (mega health, armor, etc.) to judge item control

1. Moved gametype to the left
2. Server name display, colorized
3. Custom server logo
4. Bigger, clearer team score
5. Custom team names (set by either admin or vote)
6. Team's average ping
7. Good ping is shown as green
8. Country flags (can be disabled)
9. Player's medal count

Special HUD for spectators in teamplay games.

1. Bigger, clearer team names (can be custom!) and scores
2. Weapon being currently in use by each player
3. Player names, health and armor
4. Clear display of dead players
5. Bigger, clear display of the player name you're spectating

Medals that can be earned by doing certain feats in battle (impressives, airshots, humiliation, electro combo, telefrag, defense, assist, etc.). You get a visual cue and announcer sound when you get them and the total is shown below the scoreboard.

When you pick up an item the time, icon and name of the item is displayed in the left bottom corner (time can be disabled).

Whenever you get hit by an enemy, their name will appear in the top right corner.

For easier recognition spectators get a (s) tag, dead players get a (DEAD) tag (ie Clan Arena), team chat gets a (Team) tag, etc.

The countdown for game start now has a title that shows the game type. In Duel it shows the players who are about to duel.

In team play, a new clearer panel displaying only the team names (can be custom!), team score and alive players (in CA/FT) replaces the regular score panel.

(Deathmatch) Frag message displays your current place.

(Warmup) When a player is ready to start it displays an audible and visible alert in the chat.

Timer now has a small subtext that displays the current game phase (warmup, intermission, timeout, overtime #, sudden death).

Currently if two or more announcer notifications are received, the announcer sounds will play simultaneously, making the speech unintelligible. I developed a queue that waits until one announcer sound ends before playing the next one.

Now you get an announcer notification if you took or lost the lead (deathmatch/duel) or your team took or lost the lead (teamplay).

Now the announcer announces in relation to your team in CTF (Your team took the flag/The enemy took the flag instead of Red flag taken/Blue flag taken).

Currently the timeout feature works by slowing down the game to a very low number (0.001). Sadly this breaks some things like ping/pl display and changing teams. I've changed the timeout code to stop all physics and timers instead, while keeping the game running at normal speed.
