[Vcb-framework] feedback to autoconfig.xml

[<Hov...@ly...>]

1. By autoconfig I did not mean system config. Just executable Jar file if
we start it without parameter will look for autoconfig.xml in the current
directory. It is like having default command line "mainclass
autoconfig.xml", although it we want to start with another config we just
need to provide another command line "mainclass anotherconfig.xml"

2. We agreed that need RC also in the system config. TestUI should initiate
also RC instantiations. The only difference is that RC knows about itself
and will not create new instance but rather will call its own methods.

3. I understand that you put it under system but TestUI should not be a part
of system. My suggestion is to create a System device which will contain
ModelConfig and RC (maybe a few more) and have TestUI communicate with this
device and not directly with ModelConfig. Then we will have clear separation
of logic and UI. Thoughts?

4. Last time we seems agreed to have one error outpin with message and error
code. That will simplify the picture and code. Error message should also
contain the part/connector id which it failed to add/delete etc.

5. Intuitively I feel that if we go that way that framework will keep the
queue internally we may need to have also a framework part so that other
parts can call its services (e.g. to get the queue and display it during the
testing stage). Quite similar to RC case.
