Missing check when write to "unwriteable" log-file

[Pierre-de-la-Verre]

2nd priority, but could happen ..

When the user defines a log-file which cannot be created (write protection; no access right), the ilivalidator just ignores this problem and starts the check without a message - and without a log-file.

Suggestion:
Add a "is the log file really created - check" and inform the user:
c:\no_rights\locked\already_opened.log can not be created. Please select another path / name.

Can not reproduce. I see a proper error message on the console:

log\ce.txt (Access is denied)

I use the GUI, with new version 1.11.4.
When I select the file with the "file dialog", then I get an alert "Unwriteable". But when I just enter the filename into the dialogue, then it behaves as described.
