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.
Helpers
This directory contains helper functions used by views. Helpers are used for simple common functions, such as linking to users or formatting timestamps.
Helper functions are globals. If you see an unnamespaced function in a view, and it's not a Rails function, then it's probably a helper defined here.
All helper functions defined in this directory are globally available to all views. They're not limited to single views. For example, the functions in posts_helper.rb are available to all views, not just to app/views/posts.
The use of helper functions should be minimized. Partials or components are preferred for more complex widgets, or for things used in only one or two places. Helper functions should be limited to very simple things used in nearly all views.
