Created general ROS msg package for Sample Return.

Messages and services that do not fit in a specific package
should be put here.
Added ROS msg dependencies to our msg packages.
Changed maintainer to Russel.
Add modified camera1394 package
Sync camera params between pairs
Set strobe argument for navigation cameras

Multiple cameras on the same harness shouldn't be strobing, so only
allow one pair to have a strobing master.
Fixed conditional tags for strobe
Need larger packet size for triggered cameras
Switched to pairwise harness
Adjust steering offsets
Added Hydro-compatible sbpl lattice planner code
Added Ackermann motion primitives and sbpl config
SBPL test environment is working using a first-pass motion primitive file

Run the test sbpl launch file to test sbpl (using rviz)
First pass of the Smoooooth local planner
The smooth planner receives paths from SBPL lattice planner
Changed the smooth planner topic subscription name and added remap
The Smooth planner receives path messages from SBPL
WIP - the smooth planner code to compute and assign times and velocities to a path

This does not compile yet.  I just want to check point my work thus far
Fixed compile errors and added rviz Marker visualization publishing
Fixed runtime .so link issues and added vector marker visualization for velocity along path
