Restricted Area Rework

Build: 3.10

Category: Gameplay

Progress: 12/12 (old 8/12) task completed.

Status: Polishing

Refactoring and fixing many internal issues regarding restricted areas to make them easier to setup and use. This will include landing splines, allowing ATC to open up paths for players to enter the restricted area and fly to a landing pad with guidance. These areas will become more natural and won't require obtrusive materials to show their presence.
