DRY up actions

[Will-Sommers]

One thing we do in our app is something like this

_.reduce([ "ACTION_ONE",
"ACTION_TWO",
"ACTION_THREE"], function(action, memo) {
memo[action] = action;
return memo;
}, {})

http://underscorejs.org/#reduce

We then put all of our actions in a single file and export it. In most big apps, this might not make sense but we don't have that many actions.

This might help with the readability of this file: https://github.com/wismer/dm-tool/blob/master/src/redux/actions.ts#L117

@Will-Sommers is that similar to

import * as actions from './actions';
