RS232 is working, terminator choice too

To much rubbish in the receiver.
Autobauding is working!!!

Autobauding finally works, it is magic!

Really lads, the code I have written is so awful I can't even look at it

Vel changes.
Ping funcionality added.

It was NOT tested yet.
Ping is fully operational!

bug: main window is broken, the log space is too small and it is getting
bigger and bigger when new log message arrives.
Bugi z wiki

-zmieniono konstruktor klasy Transmission, teraz przyjmuje on jako
kolejny parametr delegata na funkcję zapisującą do logu, pobierając�
jeden argument typu string
-wartości comboboxów wyświetlają się poprawnie
-okienko logu POWINNO pokazywać się poprawnie
-jak jest "received data", to niech będzie "transmitted data"
-nie mam jak poprawić tego logu z autobaudingu, ale funkcja wygląda
orajt
-są inne funkcje, niż port.ReadExisting()
Ping updated

I hope I did not destroy anything. ;)
