Automate the tarball release process

[dvzrv]

Is your feature request related to a problem? Please describe. A new release has been tagged 4 days ago: https://github.com/monocasual/giada/releases/tag/v0.19.0 The combined source tarball for this release is not available though

Describe the solution you'd like Either automatic pushing of a source tarball to a github release and/or website.

Describe alternatives you've considered Build from git repository instead (needs locking of git commit checksum)

Additional context As downstreams monitor the releases of upstreams using tools such as nvchecker, the most convenient way is usually to track their upstream repository for new tags (thus releases). This issue has been around for a while (see https://github.com/monocasual/giada/issues/399).

Yes, currently the upload of binaries + source tarball on the website is a manual process. A good improvement for the 1.0 release, when the website will be redesigned.
