Early pre release for 3.8.1 (Nightly 2)

[ann0see]

As you might have noticed, you can grab a new non-production ready Nightly of Jamulus here: https://github.com/jamulussoftware/jamulus/releases/tag/r3.8.0devNightly2

Although there might still be some features which should be included in r3.8.1, we'd be very happy if you already tested this nightly for bugs and raised them as a new issue here: https://github.com/jamulussoftware/jamulus/issues

The current status of Release 3.8.1 can be found here: #1972 (New features will probably not be included in r3.8.1)!
