Reduce size for server bundle

[MrEfrem]

It is possible to reduce server bundle several times if we exclude from it node_modules (https://github.com/MrEfrem/react-redux-starter-kit/blob/master/build/webpack/server.js):

name    : 'server',
  target  : 'node',
  entry   : {
    app : [
      paths.src('entry-points/server')
    ]
  },
  externals: fs.readdirSync('node_modules').filter(function(x) { return x !== '.bin' }),
...

And also I would clean UglifyJsPlugin from bundle, because differently in case of an error in stack trace it isn't clear where in bundle to look it.
And generally what sense in it for NodeJS to squeeze bundle?

[MrEfrem]

Still it is necessary to add

__ CLIENT __: false

in "definePlugin" for server bundle and

__ SERVER __: false

for client bundle that in both assemblies there were no errors like

Runtime error: __ CLIENT __ is undefined

on server side and vice versa.

Wow that's brilliant, never even thought of that. I'll try to get this in in the next day or two. Thanks!

Also I definitely agree about getting rid of uglify for the server bundle, good point.

Implemented both of these in #100. Thanks for the idea!
