Use full version number in the release tarball name

Right now openvpn-gui tarball only has the major version in it, e.g. openvpn-gui-11.tar.gz. It would be good to have the full version in the tarball name for at least two reasons:

• All the components combined by openvpn-build would be identifiable exactly from a git diff. Right now we only know that a certain Windows installer bundle has some openvpn-gui-11 version, not if it has 11.4.0.0 or 11.5.0.0 or whatnot.
• Old minor version release tarballs would remain available on our download servers; right now they get overwritten on every openvpn-gui release.

I presented this idea earlier on openvpn-devel mailing list.

Agreed. Let's add full version info into the tarball name.

Showing the downloaded version (2.4.x) in the GUI would be useful as well.

This is one of those "nice to have" features and as such, something else seems to have a priority. If somebody implements this I will definitely review and merge.
