MultiSense ROS Driver v3.4.7

Version 3.4.7 of the MultiSense ROS driver for the CRL MultiSense line of products was released on 3/4/2016.

This version adds in support for a new MultiSense DeviceStatus message that contains information about the internal condition (power, temperature, and status) of the MultiSense.  It also replaces the MultiSense SL calibration check utility with a version that no-longer relies on a MATLAB runtime being installed.
