Tell the user what he has to do next

[mikhailnov]

It was not obvious what had to be done after running uxplay. I have added some text, telling the user what he has to do next.

I have also made an icon and desktop file in the ROSA Linux package of uxplay (see https://abf.rosa.ru/import/uxplay).

Now users can launch it without a manual. It is worse than a GUI, but better then nothing, I think.
