ParkingPilot and fixes

[rmegyesi]

Features implemented in this pull request:

• World: NPC cars spawn in parking places
• ParkingPilot: Searching for free parking place
• ParkingPilot: Manouver car to parking place
• ParkingPilot: Can be enabled/disabled using P key
• ScriptablePath: Objects can be rotated to Waypoint rotations
• ScriptablePath: Smooth rotation using linear interpolation

Changes:

• ScriptablePath: Path now uses Waypoints instead of simple Vector2D-s

Fixes:

• NPC: Changed pedestrian rotation pivot to image center
• NPC: Crosswalk start and end waypoints now respect the crosswalk rotation correctly

Implementation notes:

• Free parking place searching is implemented in ParkingPilot component as sensors were not provided
• Manouvering uses preset paths
