Provide configuration for some issues to prevent being resolved

[jonespm]

In UDOIT 2 issues that could be fixed by UDOIT couldn't be marked as resolved. In UDOIT 3 there seems like a gap from the previous version.

For example an issue like "Avoid Using Color Alone for Emphasis" has ways that this can be fixed by UDOIT, so it seems like it shouldn't be able to just be skipped. It would probably need a configurable list of issues that can be by marked as resolved if UDOIT can't fix them.

This may be needed if UDOIT identifies an issues as a false positive, but those might also need to be filed as issues.
