check-debian-restart. Detect kernel upgrade.
Merge branch 'check_kern_upgrade' into dev
check-debian-restart. More strict version matching.

Make more strict version mathcing, so if new installed version is shorter and
is part of current used kernel version (e.g. new version 3.2 and used version
is 3.2~bpo), this will still trigger "kernel upgrade" warning.
Merge branch 'fix-not-exact-kernel-version-match' into dev
Add README.
Merge branch 'release-v1.0.2'
