* document or fix virtual channel behaviour (state is preserved)

0.9.9:

* Restart

1.1:
* Enhance Dbus API: AllocChannel(i), CloseChannel(i), CloseAllChannels(), ListChannels(), 
Quitting(signal), GetNumberOfChannels(i)
* Automatic device detection and/or device plugins?
* More support for working around different modems' problems
* Maintain device database for maximum numbers of allowed channels
