Use "zoom to fit" as default

[simurai]

Description of the Change

Changes the default to automatically resize an image to fit the available space.

Before	After

• Also disables the "Zoom to fit" button once it's selected.

Alternate Designs

It could also be a config, but even then (another PR), "zoom to fit" is still the better default.

Benefits

Able to see the whole image without having to click buttons.

Possible Drawbacks

Changes the default and might upset some.

Applicable Issues

Closes #55

LGTM! This is unrelated to this PR I suppose, but when the zoom to fit button is "disabled", it still looks like a clickable button to me. This seems like the case before this pr too.

/cc @BinaryMuse for review

The blue should mean "it's active", but yeah, to be consistent, the "Auto" button should be blue too once you start using the -+ to zoom. Made a new issue about it: #118

@BinaryMuse do you have a few minutes to review this?

[simurai]

Ok, now that @TimvdLippe approved, we can merge it. 😄

On a serious note, it shouldn't be too risky and we have still a few weeks to test on master before it moves to Beta. 🚢

It was the nicest way of saying: "oh yes please" without seeming to nag about reviewing time ;)

[BinaryMuse]

Apologies @simurai and @iolsen that this totally slipped off my radar! X_X

Was this merged in? Running Atom 1.19.2 and image-view 0.61.2 and zoom-to-fit is not default.

@aioue The fix is in Atom 1.20 currently in beta.
