Initial release for hydro

This is a tested initial release for the JACO/MICO arm that works with ROS Hyrdro. It adds the ability to use multiple arms and adds support for the 5.01.01 drivers/API from Kinova.

This release incorporates usability and stability improvements and there are some minor changes to the ROS interface in order to better track the ROS style guide.
