Latest IceWM 1.8.1 available

For those using testing or sid repos, there is an automatic upgrade the the very latest IceWM version (1.8.1), which is not even in Debian sid yet.

If you want to test this out on buster/stable antiX-19 series, add dev to the antiX sources list and do

sudo apt update && sudo apt dist-upgrade

I have been running it on antiX stable for 3 days without issue.
