The DBus specification allows only ASCII characters "[A-Z][a-z][0-9]_".
Dash is illegal and therefore libdbus is complaining about our
interface names not being valid.
Before this change signals when users were joining or leaving
the voice room were not properly handled. A new signal in audio
context is emitted now and gui will rebuild the user list when it
is emitted.

Before a very complex mechanism was implemented in order to share
a vatlib voice channel resource if more than one COM unit was connected
to the same channel. This is now moved into CContextAudio by mapping
a COM unit to a shared voice channel pointer.

* methods for changed devices
* command parser for audio
* volume display in status bar (pseudo mute)
* removed usingLocalObjects() now in CContext
* removed getRuntime() now in CContext
