Add electron-redux module

[dustintownsend]

This uses the proposed changed in PR #602.
I have the need for syncing the state between main and renderer, so this is my first pass. Based on the discussion from Issue #108 I decided to try https://github.com/hardchor/electron-redux/ first. I may do another PR for redux-electron-store and an alternative.

@burkhardr can you look over this and see if I got any of the implementation wrong? I based it on your timesheets repo.

@dustintownsend Hey. Nothing glaringly obvious I can spot.
Most importantly: does it work? 😉

[hardchor]

Might be worth adding some examples of, e.g. async actions, local or aliased actions.

@hardchor do you have any insight into why the test are failing?

It is failing at replyActionMain.js at ipcMain.on. It seems that ipcMain is not importing. I assume its due to not being in electron but a test, but I don't know enough about testing to be 100%.

#573 (comment) have provided a workaround, maybe we can migrate to electron-mocha (although we have #520), but it will broken test-watch (A reason is jprichardson/electron-mocha#18).

If this is a unit test, you'll probably need to mock electron. It's slightly confusing that electron is now also the name of electron-prebuilt on npm, so whilst running tests, that'll probably be imported (rather than the actual electron helpers).

I'm going to close this for now. I'm not sure this is a good fit for the boilerplate right now. I think it would be better as an optional add on.

[hardchor]

What are the core maintainer's thoughts? I could have another go at this once the jest PR is in.

I'm not very experienced with redux. @jhen0409 and @chentsulin may have more to say about this
