Correct missing const modifier on msg param (fix #15).
Add install targets for simple_message, industrial_robot_client, industrial_utils and industrial_deprecated.

These packages were missing proper install targets, causing problems when trying to use these in an 'install space'.
Fix simple_message msg dependencies.

Identical to issue #4, but for Groovy.
Fix issue #5 (Install target fails for industrial_deprecated): setup.py file not required for python executables, see http://ros.org/wiki/catkin/migrating_from_rosbuild
Fix issue #6 (Install target fails for industrial_robot_simulator): setup.py file not required for python executables, see http://ros.org/wiki/catkin/migrating_from_rosbuild
