Keep track of ignored errors, resolves #2533

[NeoTheThird]

Users are often reluctant to report the first error they run into and chose to ignore it. If something does not work, they report it later and the error gets buried in the log. We should keep track of these and include them in the bug reports.

If any errors have been ignored, the PASS reporting option should be disabled. Even if everything worked, the correct status to report in this case is WONKY, as a workaround was required.

Turns out I only have two pretty opinionated comments, LGTM otherwise so feel free to ignore :)
