Add redux-define

[smeijer]

I would suggest adding redux-define to the list.

It's a small helper (something like 500 bytes) to greatly reduce the boilerplate code of defining action type constants.

Neat, although the added value feels a bit too small. You can add it to http://devarchy.com/redux and I'l merge it if enough people upvote it
