make-release: Adapt for git repo instead of svn

Functionally equivalent to the old script except:
  - use git repository instead of SVN
  - do not push the local git changes to any public repo
    (unlike "svn tag" does)

Note: The workflow regarding tagging, pushing the tag,
      building the sources, and uploading the source
      tarball and windows installer might need rethinking.

Note2: The "release resides" output probably was not
       accurate before regarding the location of the
       Win32 installer, and now is probably using a
       different directory.
