[Improvement] "Unsure" dialog option

[jvook]

While bisecting it's possible to come across an unstable or otherwise a build that does not allow the bug to be tested. After closing the program, the bisect tool asks "Yes" or "no" whether the bug occurred. If the bug wasn't able to be tested this throws off the progression of the bisect. An "Unsure" option that simply ignored the results of that particular test and went on to another build would help.

Hrm, that's a good point.

I think something like this could be implemented. I just need to think of how I want to implement this.
