[WIP] Use Bublé instead of cursed Babel

[danielkcz]

Just little experiment to contradict #266 with this little unknown transpiler. First impression is that it's faster then babel and there is couple of bytes saved as well. I absolutely love that it doesn't need any configuration. Just use plugin and done.

Current babel configuration (master)

Using Babel 2015 preset (@Piroro-hs)

Using Buble
Estimating dist/stampit.umd.min.js: 4.5 KB, GZIP : 1.52 KB

Here I made a package of all three approaches for comparison.
stampit-dist.zip

The PR needs some cleanup, just wanted to do a quick check.

Wow. Cool! Can we kill package.json->babel too? Please :)

[danielkcz]

Ok, got rid of Babel, although we still need babel-cli to actually run the build because Buble apparently doesn't have alternative to babel-node :(

Looks like this PR needs to be improved because the folder still contains the bloody .babelrc file. That's one of the issues with the react-native.

Yea right, I've missed that :)
