All the service staff v1.6

This is an updated and expanded version of the old Dispatcher mod. I've added customer service staff into some more places, not considered by the author of the original mod and hidden the other active area indicators.

Changes in v1.6:
- Updated for Road to the Black Sea DLC: active area indicators at weigh stations have been hidden (similar to tollgate ones)

Features:
- Dispatcher at companies and ferry terminals
- Customer service staff at truck services, recruitment agencies and truck dealers
- Seller near garages
- At gas stations, tollgates, country borders, weigh stations, railway stations and inside the garages active area indicators have been hidden

Compatibility: 1.35.x - latest
