Fixes issue with Mission Overhaul: Core where requested evac made the mission placed evac zone disappear.

Fix bug where only the first Evac would work (courtesy of Iridar)

Fox Update (courtesy of Iridar):

- Adds Russian localization.
- Request Evac ability will be put it on cooldown upon activation until Skyranger arrives and leaves.
- Maximum range between squad and randomly selected evac location reduced from 20 tiles to 10.
- The delay before evac arrives is no longer random by default, and equals 2 turns.
- Improves stability, compatibility and performances.

Added AlwaysOrientAlongLOP flag, default to false.
If true, will always strongly orient evac location towards the line of play.

Removed debug logs.

• Change how we search for an evac location.
  
• Display the time remaining for the evac zone to appear. (Thanks to LW implementation)
  
• Display the time remaining for the evac zone to disappear.
  
• Now use LW assets (flare, Firebrand dialogues)

• Added TurnsBeforeEvacExpires: Evac zone will disapear after X turns - default 3 (Iridar's idea)
  
• Added DisplayFlareBeforeEvacSpawn: If set to true a flare will mark the area where you will be able to evac one turn later. (MrMister's idea)

Initial release.
