Summary: Error in renderind disconnected MSC

Initial Comment:
I've noticed SCstudio has a bug in import function, when rendering of disconnected MSC.
When a new instance of a node pops up, the messages are placed at the beginning of the .vsd file,
they should be always added after the last message.

Having multiple interfaces (IPaddresses) is quite common in SIP applications.

In the attachment an example of SIP Call Flow, where the rendering is incorrect.

Message:
Actually, it is a basic feature of MSC that disconnected events on
different instances can be placed arbitrarily. 

I suggest two solutions:
- consider the interfaces of a single computer as standalone components and
add some messages between these interfaces representing internal
communication proceed within the computer; hence, the relevant messages
will not be disconnected any more. (Ok. this should be hardly achieved from
pcap. )
- consider the multiple interfaces as nicknames of the same computer and
make a single instance representing all of them together (Matus, is there
any possibility to specify this by parameters of pcap2z120.py?)
