[WT-support] A couple of SSB things

[Jozef Urban, OM7ZZ]

It´d be great is this works so that so that I can at least select as
an option that
- DVK message is played even if footswich is pressed
- Footswich and DVK messages would be chain able so that when I release the
footswich the DVK message is played

Toni,

Both above works if Router is set to do this.
To accomplish what you want, set Audio switching to "CmCmCm, voice codec 
SC1" (Audio Switching tab) and PTT sequencer to "Restore serial PTT and 
audio routing" (PTT/FSK tab).
