Factor out thumbnail galleries into a PostGallery component. This changes the html structure so that post galleries on all pages are always wrapped in a `.posts-container` class. This fixes an issue with thumbnails on the pool show page not being aligned correctly on mobile, like they are on the post index page. This also affected thumbnail galleries on other pages, like wiki pages and user profiles.

# A component that displays a gallery of post thumbnails.
|
|
#
|
|
# There are three types of galleries:
|
|
#
|
|
# * Paginated galleries, as seen on the post index page and pool show page.
|
|
# * Unpaginated galleries, as seen on wiki pages, artist pages, and user profiles.
|
|
# * Inline galleries that fit on a single row, as seen in parent/child post sets.
