Major refactoring
Renamed AircraftGenetator to FlightPlanComponent to better represent its
name, also moved to controllers.components subpackage as it is a helper
for a controller
Renamed WaypointData to WaypointComponent, moved to
controllers.components, same reason as above
Moved createWaypoint to WaypointComponent as it makes more sense
Removed some unnecessary comments
Renamed screen.shapedebugger to shaperenderer as it's not used only for
debugging
Also fixes #52
