Use object-cover for author images unless AR is really high or low

[mikiher]

While working on lazy loading the Author's page, I felt that we're using object-contain on author images too much - while this works nicely for covers, I feel (subjecively) that the author images look unpolished when we use object-contain. So I modified the current decision algorithm for using object-contain to only use it when the AR is very high or low.

Here's my author page before:

And after:

Some of the more significant changed are marked on the After screenshot.

I guess it's really subjective, but I find that I like the After much more, even though in some cases (e.g. John Scalzi), it results in a slightly cut image - but I think in those cases the original looks quite bad as well.

I guess I should also work on allowing users to upload their own author image...

I agree it looks better for my authors also.
We can probably remove that functionality altogether and use object-cover. An image with an aspect ratio < 0.5 or > 2 will probably display worse when it uses object-contain.
Maybe after the next release if users like using object-cover
