[1.0.0.92] Ignore identical changes in retrofitting preview

[Xyquas]

When I open the retrofitting panel for a fleet and choose my target design, I get a preview with comparison on the changes made to the design (which is a really great feature! *thumbsup*). But the "change" from let's say 3 regular lasers to 3 regular lasers should be ignored.

Explanation:
I have a ship design, let's take the cruiser for example, and modify this one in the design view. I add a bunch of antimatter torpedoes and some shield while removing some lite lasers for getting the needes space. In this design phase I play with my current weapon stacks changing 3 regular lasers down to 2 and in the end back to 3 again because I found another system to kick out of my design. When I save this design and want to retrofit an previously built ship of this design, I'm told that my 3 regular lasers have changed to 3 regular lasers - which is correct considering my clicking history but not for the result I had produced.

Thanks for reporting, I have created an internal ticket to track this issue.
