Gallery: fix image size select

[designerbrent]

One quick (i hope) issue to address on this: It is forcing all the images into a horizontal aspect ratio by cropping the images to a horizontal image. Can we display the image in the correct aspect ratio?

Added new class to ALPS for this fix. Please merge the https://github.com/adventistchurch/alps/issues/490 first

I've merged the https://github.com/adventistchurch/alps/pull/490 PR but haven't seen any change in the behavior of the gallery yet.

adventistchurch/alps#490 adds u-background--contain class to the ALPS css. Current PR will change Gallery behaivor.

I'm seeing no change in the gallery, even after pulling this most recent change of this PR. What I'm seeing on the back-end of this, and a newly inserted gallery is this:
