Asynchronous Actions

Database actions might take a long time, same with synchronization actions. Perhaps we need a way to do asynchronous effects.

This article seems to do a fairly comprehensive comparison of the available options related to redux https://sandstorm.de/de/blog/post/async-redux-middleware-comparison.html

[redux-loop](https://github.com/redux-loop/redux-loop) appears to be the most simple solution, basically, basically just an async call from the reducer which dispatches an action back on the store upon completion.

Start by reviewing the linked comparison of Redux middleware options and the redux-loop project. Then trace the database and synchronization actions to determine where asynchronous effects would fit and how completion should dispatch back to the store. Done means the project has an agreed, working approach for long-running actions.
