Organise API endpoint utilities
Just re-organising the functions into separate files for now. I've split the IDs server endpoints into their own file too and added an
ids.js config file.
Usually, the functions in an
api folder return promises (e.g.
return axios.get(...)). At the moment,
axios is called in action creators. Since we're gonna move to Rest Hooks and remove a lot of these actions, I didn't bother changing anything on that front.
