posts: add adjustable thumbnail sizes (#4932).

Browse Source 
Add a menu in the top right of the post index page that lets you select
the thumbnail size.

This menu is currently hidden until the new thumbnails have been generated.

On desktop, there are five thumbnail sizes:

* Small:    150x150 (https://danbooru.donmai.us/posts?size=150)
* Medium:   180x180 (https://danbooru.donmai.us/posts?size=180)
* Large:    225x225 (https://danbooru.donmai.us/posts?size=225)
* Huge:     270x270 (https://danbooru.donmai.us/posts?size=270)
* Gigantic: 360x360 (https://danbooru.donmai.us/posts?size=360)

On mobile, there are four sizes:

* Small:  150x150 / 3 posts per row (https://danbooru.donmai.us/posts?size=150)
* Medium: 180x180 / 2 posts per row (https://danbooru.donmai.us/posts?size=180)
* Large:  225x225 / 2 posts per row (https://danbooru.donmai.us/posts?size=225)
* Huge:   360x360 / 1 posts per row (https://danbooru.donmai.us/posts?size=360)

There are two extra sizes that aren't listed in the menu:

* 225x360 (https://danbooru.donmai.us/posts?size=225w)
* 270x360 (https://danbooru.donmai.us/posts?size=270w)

These sizes are good for tall thumbnails, but not so much for wide
thumbnails. They aren't listed because in practice they're a bit too big.

The 225x225 and 270x270 sizes are really just 360x360 thumbnails scaled
down in HTML. This means 225x225 and 360x360 thumbnails both use the
same amount of bandwidth.

Thumbnail size is currently a per-search option, not a persistent
account-level setting.

This changes the HTML structure of thumbnails somewhat, so this may
break userscripts and custom CSS.
