Remove version.mk and references to it in the repo.
genversion.bat will now generate the same version strings as
update_version script, i.e. without 'v' prefix and without a
fallback if git archive is used.
If run from a release tarball it'll use package_version,
like configure. If run from a git repo, it will use the same
'git describe' with '-dirty' as update_version.

We released 1.1 with 1.1-beta as the hard-coded version.
Hopefully this only affects people doing their own windows builds
without the git tools available.
Thanks to Ron Lee for the report.
