Version stuff in CMakeLists.txt

[Dag]

I can't figure out how this is meant to be used.

We have now released 3.0.0.1. Next should probably be 3.0.1.
So I gather current should be an alpha:
Major: 3
Minor: 0
Release: 89

But then we would go backwards to Release: 1 when releasing,
and after that we go to Release: 89 again and we can't see
what 3.0.89 actually means as it will crop up for every new 3.0 release.

Is it just me being confused, or...
Anybody?
