Simplify versioning by CMake. Uses git version in the format
"<major>.<minor>.<patch>.r<commits-since-version-tag>.g<hash>(-dirty)?".

Adapts Doxygen generators to changes in previous commit.

Remove CMakeLists.txt generator scripts from build phase. Replaced with
CMake's GLOB that can re-run every time the build is invoked. We can
also drop the Python dependency now.

Removed header installs which will be redesigned in future commits.

Remove Dot2 algorithm. By default, the interactive window now
does not block CLI. Added overload to override this behaviour.
