Reimplement options to lock icon scaling at 32x32/64x64/etc.

[Carver]

Per the title, it does a terrible disservice to our wonderful sprites to see them stretched or blurred unnecessarily (and the latter is painfully straining to look at). I would hope that this is still possible in some manner, though forgive me if the option is around and hidden somewhere and that I've merely been unable to find it.

I don't use it myself since my 1440p monitor doesn't play well with it, however basically everyone I've ever talked to on a 1080p monitor hates this change from months ago, their game is now blurry for seemingly no reason, bring it back

I do not believe I have this issue but I agree that it would be a good quality of life improvement.
