Confirmation in adding white list

Rubberduck version information

Description
Applying the option "Add to whitelist" from the Code Inspection does not give any confirmation or response that the fix was applied. You will have an impression that something went wrong so you will apply the fix again and again only to see that it was indeed added multiple times when you check in the rubberduck settings.

Expected behavior
Reparse after the fix was applied like how the other fix behave.

1. We cannot reparse willy-nilly. It's just too slow for many of our users still (unfortunately), and (shouldn't) be needed to update any results returned over this name.
2. It should not be added multiple times. This should be addressed.
3. We can retrigger the inspections, or maybe create a system to invalidate inspection results (maybe the inspection should get a new member IsResultInvalid(Result, Data)).

UX still demands a confirmation that something indeed happened.
