Relics mutator:

The Relics mutator spawns several relics around the map, as items that players can pick up and hold. Each player can carry one relic at a time, and drops it when they die or press the "drop relic" button. If not picked up after some time, a relic will respawn in another location. Each relic grants a special ability to the player carrying it. Currently, there are 16 relics in Xonotic.

NOTE: This mutator is not committed to master yet. To test it, see the branch mirceakitsune/mutator_relics in GIT.

TODO: Test the mutator intensively and fix any possible remaining issues.
TODO 2: Add sounds and particle effects when a relic causes an action. DONE
TODO 3: Remove Runematch, as this mutator will replace it.
TODO 4: Teach bots to go for relics, as low priority items.
TODO 5: Show the relic you are carrying on the HUD.

Relic types:

1 - Resistance: The Resistance relic protects the player carrying it, by making him take less damage. Does not work while you have the Shield powerup.

2 - Regeneration: This relic slowly regenerates the carrier's health. It's not available when normal health regeneration is enabled, and therefore will not spawn by default.

3 - Vampire: The carrier of this relic is healed based on the damage he deals to his opponent. This relic will not spawn when the vampire mutator is enabled.

4 - Ammo: Slowly grants ammo of all types to the owner. Except fuel when the fuel_regen item is owned.

5 - Damage: The weapons of those who have this relic do more damage. Does not work while you have the Strength powerup.

6 - Splash Damage: When the holder shoots someone, the damage is transmitted to those around the victim, harming them as well.
TODO: Make this relic not affect team mates.

7 - Firing Speed: The player's weapons fire faster.

8 - Disability: A player shot by the owner of this relic is cursed for several seconds. Curses include: Slower movement, lower jump height, slower firing rate.
TODO: Add effects to the players cursed by this relic, such as particles and sounds. DONE

9 - Team Boost: Players carrying this relic boost team mates that get close to them. The boost also lasts for a few seconds after they leave the carrier's radius. This relic will only spawn in team games.
TODO: Add effects to the players boosted by this relic, such as particles and sounds. DONE

10 - Speed: Owners of this relic can run faster.

11 - Jump: Helps the player jump higher.

12 - Flight: Players fly around when they pick up this relic (just like observers)

13 - Invisibility: The player becomes transparent, making him harder to see and hit. This relic will not spawn when the cloaked mutator is enabled.

14 - Radioactive: Those who get too close to the holder of this relic will take damage.
TODO: Make this relic not affect team mates.

15 - Resurrection: If you die while holding this relic, you will be revived with your health to default spawn value. The relic then respawns in a different location. Does not work for suicides.

16 - Vengeance: When the carrier dies, he causes a big explosion that harms anyone who is close. The relic then respawns in a different location. Does not work for suicides.
TODO: Fix explosion particles, which are not showing for some reason.
