Title: Document unreliable screenshot

Reasons for documenting this, rather then silencing the error:

(1) Errors should never pass silently.
(2) Unless explicitly silenced.
(3) I want the user to make a choice about whether he wants to retry making
the screenshot or whether he doesn't care for it.
(4) I don't want to re-invent Robot Framework's machinisms for retrying and
silencing errors

This gives a specific error message for the backend's explicit
"Screenshot not available" status, so one can handle it in the test script.
