Replacement of the datamatrix with fast RGB-D circle detection

See the relevant README.
This adds unnecessary dependencies to scitos_msgs, scitos_apps, and actionlib. Can you please replace this with:
```
add_dependencies(social_card_reader ${catkin_EXPORTED_TARGETS})
```
This adds all the generated targets you can depend on from the packages you listed in line 7.
Please also add dependencies for the libraries if they are using ROS components.
