New release 3.0.1

This is basically a bug fix release with the following changes:

- bug fix: buzzing occurred when audio stream was interrupted (e.g. in case of network trouble)

- in case "Open Chat on New Message" is not enabled, a hint in the status bar is shown when a message is received

- use low complexity CELT encoder profile, this lowers audio dropout
