add `upowermon` (upower battery state monitor)
upowermon: fix checking state
upowermon: implement notifications
upowermon: set timeout for notifications
Merge (import upowermon from code recycle bin)

It seems to be useful, so might as well put it here.
perl-lspkgs: add debug logging of which file is being read
check-ldap-sync: add radian temporarily

It seems to be up again, but I've no idea who brought it back up nor
why, therefore I won't be adding it to _ldap._tcp for a while yet.
