Damage from spectator players is now blocked to avoid insta kills from trolls shooting grenade launcher and going spectator.

Added 2 new settings: can_cast_votes, ricochet_burn_damagefactor.
See HERE for the details of the new options.

Added a fix for the game glitch that removes the boomer bile effect on the screen after going inactive.

Restored the friendly fire feedback when ricochet mode is enabled.
Now the character yells at the attacker even though the damage received is pretty much 0.
Friendly fire counters at the end credits will show the correct number instead of 0.

Little fix to the previous change

Moved friendly_fire from l4fcvars to settings
