Title: Allow custom formatters to be set with API settings.

Due to their close relationship with content-types, it seems obvious to allow custom formatters to be set in the same way.

Reading the code, and how it is structured, it seems strange this setting is not already available. If this is already available in another way, I completely missed it and this pull request can be closed immediately (I'll submit another pull request to update the documentation so the existing functionality is explicitly mentioned).
