Subject: [PATCH] Cell Broadcast message decoding and presentation in libgsmd-tool.

This time Cell Broadcast is tested to work, I should have made tests earlier. 
Now I'm correctly getting a CB message with the human readable name of the city
and district when I'm connecting.  In the previous patches the CB PDU was not
being decoded at all.
