RunCam initialized, features 0x0x…, N-key OSD

Good news at start-up. “Camera: … fw:…” is a MAVLink camera giving its maker, model and firmware version. “RunCam initialized, features 0x…, 5-key OSD” is a RunCam camera listing what it can do; “0-key OSD” means its menu cannot be driven from the transmitter. “CAMERA_INFORMATION … set from script” means a Lua script supplied the camera's description for the ground station.
