 * this replaces kcmlaptop - there are 2 parts - one is the panels that
 *	put the setup configuration in the "kcmlaptop" configm, the other
 *	is the laptop_daemon (this guy) who watches the battery state
 *	and does stuff as a result
 *
 * This file contains the implementation of the main laptop battery monitoring daemon
