Add a --output_file_prefix option to the asset writer. (#537) 

It defaults to using the first bag name, i.e. the files end up next to the input file which is more ergonomic than having them end up in $HOME/.ros.

At the time of writing, the generated assets end up in ``~/.ros``.
All output files are prefixed by ``--output_file_prefix`` which defaults to the filename of the first bag.
For the last example, if you specify ``points.ply`` in the pipeline configuration file, this will translate to ``${HOME}/Downloads/b3-2016-04-05-14-14-00.bag_points.ply``.
