Implemented temp sensor detection for linux, it is basically a light
detection, most info came from the temperature module,
_wizard_temperature_get_bus_files == temperature_get_bus_files from
temperature module. tested on 4 systems, and one really old system
which does not have sensors and it seems to work very good.
