This file provides our Redux reducers related to local settings. The
associated actions are:
- __`STORE_HYDRATE` :__
Used to hydrate the store with its initial values.
- __`LOCAL_SETTING_CHANGE` :__
Used to change the value of a local setting in the store.

Helper functions:
-----------------
### `hydrate(state, localSettings)`
`hydrate()` is used to hydrate the `local_settings` part of our store
with its initial values. The `state` will probably just be the
`initialState`, and the `localSettings` should be whatever we pulled
from `localStorage`.

/*
`localSettings(state = initialState, action)`:
----------------------------------------------
This function holds our actual reducer.
If our action is `STORE_HYDRATE`, then we call `hydrate()` with the
`local_settings` property of the provided `action.state`.
If our action is `LOCAL_SETTING_CHANGE`, then we set `action.key` in
our state to the provided `action.value`. Note that `action.key` MUST
be an array, since we use `setIn()`.
> __Note :__
> We call this function `localSettings`, but its associated object
> in the store is `local_settings`.
