Suggestion: Show drive temperature

[bigntallmike]

Since it's already linking against the appropriate libraries, displaying each drive's temperature (on the line where the drive's wipe status is updated) would be useful for knowing if the system is handling necessary cooling properly.

Of course actually pausing when over temperature would be nice too, but just displaying the temperature would be a start.

Sounds like an interesting addition.
