New "warning" value for "onexception" and for "onerror"

[FherStk]

Te easy way should be to add a "warning" option within question to set the caption, and also allow a "WARNING" option within onexception and within onerror.

Within onerror, "CONTINUE" will work as usual displaying ERROR or SUCCESS, but "WARNING" will display the error message as a warning, and will continue with the execution assuming there was no error (like a success, but displaying a warning and also scoring).
