Robot error handling: better visual feedback

[lorenzleutgeb]

If I move my robot out of bounds, it just disappears and it is not apparent what happened. There should be better feedback actually telling me my bot went OOB and I need to fix it.

there should be an alert

I did not get that alert (don't ask me why).

[victorbalan]

maybe you have alerts disabled. I`ll work on a general paper dialog with a title and a message that we can display in such cases.

[lorenzleutgeb]

I have not.
