Title: Added sensor_msgs/Temperature Display.  Added ability to invert rainbow ...

...colors for point cloud common.

Added the sensor_msgs/Temperature. Since rainbow didn't make sense, I added a boolean to invert rainbow colors on RVIZ (blue is low, red high). Then I was able to make invert rainbow used for Temperature.

This way ice is blue and fire is red.
