Title: Thermal Sensors Widget (for pfSense v2.1-BETA1 and up).

Original post: http://forum.pfsense.org/index.php/topic,59193.0.html
NOTE: I've changed the widget name from "Core Temperatures" to "Thermal Sensors", which I think is more appropriate.

Description:
Thermal Sensors Widget is a stand-alone widget.
No existing/original file changes required.
Displays Thermal Sensors data for anything returned by "sysctl -a | grep temperature" command (in will fall back to "No Thermal Sensors data available" message if no data available).
Configurable thresholds and display appearance.
NOTE: depends on proper cofing in System >> Advanced >> Miscellaneous tab >> Thermal Sensors section.

Designed and tested for:
pfSense 2.1-BETA1 (i386)
Browsers: FF, Chrome and IE9.
Hardware tested on: Intel DH77EB, Core i3 3225
