Comment 2 for bug 1026412

Added a new plugin in https://github.com/alexmurray/indicator-sensors/commit/4923925071c5dbadd00f63563a6a96f9b4b4905c called 'max' which creates a virtual sensor which displays the label, icon and value etc of the sensor with the highest reading at any one time. This can then be selected as the primary sensor to display in the indicator and it will always reflect the highest sensor's details.
