PR: Merge dev v0.4 to master (#13)

* Added some sites to black- and whitelists

* Bump version; added new copyright year (in anticipation ;-)

* Add booking.com URL referer to whitelist; needed to unsubscribe from newsletters

* Added 1Host/Pro blocklist

* Added dlvr.it to whitelist (used by Debian News microblogging as URL shortener service)

* Added de.amazonforum.com to whitelist

* We now stop pihole-FTL before import and start it again afterwards to get rid of all DB locking issues;
also changed shell variable quoting

* Added info.jetbrains.com to whitelist

* Added error handling and runtime statistics

* Added new blocklists; added new whitelist entries; small code improvements

* Removed non-existent (abandonded?) list

* Added /usr/sbin to $PATH; for execution through crontab entry, we need the /usr/sbin/service command

* Added api.segment.io (Docker desktop diagnostic API call test) to whitelist

* Revert "Added api.segment.io (Docker desktop diagnostic API call test) to whitelist" - this is a marketing tracker API service => BLOCK!

This reverts commit 9933e6f3b307265a313555f9da06b1c81bc516bc.

* Updated README.md for v0.4
