Refactor Containers and Routes in order to make the code a little more
readable, reduce duplication, and prepare the codebase for integration
of the new Home screen.
- Break out the Root container into several smaller containers that are
responsible for connecting themselves to the Redux store.
- Use routing for navigation between primary containers
- Unbundle the `Syncing` Component from the Onboarding section and hook
up to router so that it can be access by navigating to `/syncing' (we
want to be able to load existing wallets and initiate syncing outside of
the context of the onboarding process)
- Reduce code duplication
- Create `TitleBar` component and implement once at the top level
- Create `withLoading` HOC and use to display the loading screen when
needed.
By not loading locale data into the main process we can considerably
reduce it's size. We the only thing we need access to in the main
process is the translation sets (used for the languages menu).
refactor the i18n code so that the locale data can only be loaded when
needed (in the renderer).
