This rewrites the version info using lokid's approach of compiling it into a .cpp file that gets generated as part of the build (*not* during the configure stage). Among other things, this means that changing the version no longer invalidates ccache or cmake dependencies, and because it depends on `.git/index` git commits will cause the version to be regenerated, making the commit tag more reliable (currently if you rebuild without running cmake your git commit tag doesn't update).
