Changed to use right topic names and to record all topics except the camera streams in rosbag

Changed to use right topic names and to record all topics except the camera streams in rosbag. Also mapped some parameters from strandsbag into rosbag. This commit should make it possible to use the strandsbag for real tasks. To use it do:
roslaunch strandsbag record.launch o:=(PATH_TO_BAG)/mybag.bag video_path:=(PATH_TO_VIDEO)
roslaunch strandsbag decompress.launch video_path:=(PATH_TO_VIDEO)
roslaunch strandsbag play o:=(PATH_TO_BAG)/mybag.bag
What remains is mainly to test it rigorously on the robot and add online decompression.
