prepared changelog for release 2.2.0 (#82)

moved entries in changelog from `unreleased` to 2.1.0 (even
though technically it's too late for that since that version was already
released).

added new section for 2.2.0 and added some points on what changed.

bumped version to 2.2.0 in main.sh, example.sh and package.json

Closes #74
