GRAD Traffic

Alpha version, WIP

Simplistic Civilian Traffic System for Reforger.

Spawns civilian cars, drives them somewhere, despawns them. Raises some events for threat level changes:
`SCR_TrafficEvents.OnCivilianEvent.Invoke(owner.GetOrigin(), "gunfight");` and `SCR_TrafficEvents.OnCivilianEvent.Invoke(owner.GetOrigin(), "killed");`

handing over the position of the event to any script.

Sample Mission Header:

```
"m_TrafficSpawnSettings": {
    "m_bEnableTraffic": true,
    "m_sTargetFaction": "CIV",
    "m_bUseCatalog": true
  },
  "m_TrafficLimitSettings": {
    "m_iMaxTrafficCount": 15,
    "m_fTrafficSpawnRange": 2500.0,
    "m_fPlayerSafeRadius": 500.0
  }
```
