Executable Naming issues

Fixes an issue similar to https://github.com/ros-industrial/ros_industrial_issues/issues/8
Changes from version_0.x to version0 as the other naming convention gives some issues.

Tested with sda10f with normal config and with config from bmda3
All other targets in this file are prefixed with a hardcoded `motoman_`. Using `${PROJECT_NAME}_` for this target alone seems inconsistent.
