Issue Description

After Updating nuget packages, the specflow extension throws several messages regarding "Regenerate Featurefiles".

We have a solution containing several "test design" projects containing feature files. When a nuget package, that is referenced in those packages, gets updated, several instances of the same warning appear. It would be nice, if those warnings could be reduced. A single warning, with the option to regenerate should be enough. As far as I expect, a click on a single message box, regenerates all feature files and as a consequence, I would regenerate with every message box all files again.

As a quick fix, you might want to consider setting the option "Disable re-generate feature file popup" to True.
