- PARTIALLY DONE - Applet should work on virtical panels too (I have no clue why anyone would run a text based applet virtically but...).
- Autoconf check for lm_sensors
- Better "Add/Modify/Remove" sensor buttons in properties.
- Text length check to automatically set applet width.
	- Could also be used for "Add/Modify/Remove" sensor buttons.
- Make the "Add Sensor" window pop up in the center of the "Properties"
