ros & ros-listener: refactored some methods into base class
ros-service: set default ip to current (development) ip
added ros-imuconnect: Connects to IMU. Listens to /imu/data_raw and /imu/mag and visualizes output.
index.html: added d3 library
added SensorChart to display sensor data (poor performance so far...)
ros-imuconnect: use SensorChart
code improvement: removed unnecessary semicolon
ros-listener, ros-service: changed default host to be more generic
