renoise: 3.0.1 -> 3.1.0

[seanparsons]

Motivation for this change

• Bump to 3.1.0.
• Renoise non-demo builds have a licence baked into them, which means each is a totally individual bundle so SHAs can't be used.

Things done

• Updated the version to 3.1.0.
• Replaced the demo parameter with the releasePath parameter so that a path to the full version can be supplied.

• Tested using sandboxing
  (nix.useSandbox on NixOS,
  or option build-use-sandbox in nix.conf
  on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • Linux
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Fits CONTRIBUTING.md.

While I remember, it would be amazing if this could be streamlined into the 17.03 branch as well.

@the-kenny Is the 17.03 channel frozen? The current commit for it looks to be way behind even this PR.

@seanparsons The channel might be frozen, yeah. I personally don't use channels and can't say much on that issue.
