- Add ability to specify 'Display Update Frequency' and 'Sensors Update
Frequency' independantly.
- Fix the 'Apply properties' + 'click to forward display' = 'segfault' feature
- Applet should work on virtical panels too (I have no clue why anyone would
run a text based applet virtically but...).
- Ability to modify the sensor items
- Autoconf check for lm_sensors
