Code Clean up

[lucas-aragno]

hey @keyserfaty !

I've made some changes to my fork since your last update here is the changelog:

• I've added babel-plugin-transform-class-properties to the package json, if is not there webpack will fail b/c it's listed on the babel.rc
• I've replaced _.map w/ the map function builted in ES6, and since we don't need lodash for now I've removed that dependency out ( see: https://www.sitepoint.com/lodash-features-replace-es6/)
• I've also added the mapDispatchToProps function to the PostContainer.js since this is one of the best practices to deal w/ dispatch's
• Also I think it's better to pass the props to the Post component individually than make them share the scope

I think that's all, feel free to reach me out for any feedback / modification that you may think could be useful.
