Precompiled lib, use webpack and update dependency versions

[scags9876]

Some useful stuff in here, thought others might benefit from these changes.

• using webpack instead of grunt and browserify
• including babelfied lib
• upgrading dependencies to work with react 15
• upgrade to lodash 4.x

Addresses:

• Provided babelified components as part of npm prepublish #23
• NPM Package Not Precompiled #19
• ES6 module syntax? #21

Thanks very much for this! I am out of town for a week but will review this when I get back..

@scags9876 running webpack doesn't appear to create transpiled .js for distribution, which seems to be what #23 and #19 call for. Running webpack creates a bundle that includes the example application, but that isn't what we'd want to ship with npm publish.

@MandarinConLaBarba sorry for the late response, been a busy week. I believe the command to use is npm run prepublish I add a small section to the readme to explain the various npm commands. 😸

Great, thanks. I would think that the transpiled code would be included in the npm package, but not in source. Meaning, lib/*.js would be in .gitignore so that it would be kept out of the repository. Thoughts?

[scags9876]

Ah yes, you are correct @MandarinConLaBarba . I'm using it checked in so that I can import directly from github:

"react-tree-menu": "git://github.com/scags9876/react-tree-menu.git",

I can make this change... I might need to submit a new PR for it though since I'd like to do it in a branch of my fork so that I can continue to import my master until you merge this.

Ok, #32 has been opened and replaces this PR
