This PR simplifies the fixtures system and hews closer to the standard ROS way of doing things.
- All nodes are configured with a .launch config file http://wiki.ros.org/roslaunch/XML
- All configuration parameters are loaded from yaml files into the parameter server
Before: fixture -> load_fixture -> db -> launch file -> load config from db
After: launch file -> read config from param server

Note that while this simplifies things a great deal and removes a few footguns, it’s a backwards-incompatible change.
