refactor: switch to new versioning scheme

The new versioning system is based on the versioning system used by the
GNOME Foundation for the GNOME desktop.

We are dropping the "major version" as defined by SemVer and move to a
version number with a most and least significant number.

The most significant number must be incremented, if there are new
features or significant changes since last major release.

Otherwise, the least significant number must be incremented, if there
are only minor changes since the last release. New features or
significant changes mustn't be introduced by a bump of the least
significant number.

If a minor change would introduce small user-facing changes (like a
message-box or slight UI changes), it could still be classified as a
minor change.
At the end of the day, a human shall decide, if a change is minor or
significant, as there is no clear line that would separate a "minor" and
a "significant" change in a GUI-application.

Definitions:

feature: New user-facing functionality
significant change: Something that changes user-facing behavior
minor change: Something that fixes unexpected behavior
