The previous commit changed it so that `/pools?search[name_matches]` does a full-text search. So for example, `search[name_matches]=smiling` will now match pool names containing any of the words "smiling", "smile", "smiles", or "smiled". This commit adds a `/pools?search[name_contains]` param that does what `name_matches` did before, and switches to it in search forms. So for example, `search[name_contains]=smiling` will only match pool names containing the exact substring "smiling". This change is so that `<field>_matches` works consistently across the site, and so that it's possible to search pool names by either an exact substring match, or by a looser natural language match. This is a minor breaking API change. API users can replace `/pools?search[name_matches]` with `/pools?search[name_contains]` to get the same behavior as before. The same applies to /favorite_groups.

This directory contains library code used through Danbooru. This includes things like defining API clients, dealing with sources, parsing tag searches, storing and resizing images, and so on.
Many of the files here use the Service Object pattern. Instead of putting complex code in models or controllers, it goes here, in plain old Ruby objects (POROs). This keeps models and controllers simpler, and keeps domain logic isolated and independent from the database and the HTTP request cycle.
