Remove "babel" field in package.json for react-native support

[Piroro-hs]

React-native-packager try to use babel config in package.json or .babelrc and throw "Unknown plugin" error.
This PR will solve this issue and allow using stampit with react-native.

facebook/react-native#4062
react-native TransformError when requiring a node_module that has a package.json with a babel config that specifies uninstalled plugin (stackoverflow)

Wow. Awesome!
We had to put all that code for a reason probably not relevant anymore.
Let me test it back and forth. There might be caveats.
Will publish ASAP.

Cheers

Looks good to me as well. I remember (although bit foggy) that we had to do it like this because of ES2015 preset transpiling those ES modules and babel-preset-es2015-rollup wasn't working that well.

It's bit problematic, that build might actually pass, but don't have exactly tools to automatically verify that those builds are really working properly.

First of all, thank you very much @Piroro-hs for that cool deep techy contribution.

I checked the final resulting bundle.

1. The new bundle now has this code:

var _typeof = typeof Symbol === "function" && typeof Symbol.iterator === "symbol" ? 
function (obj) { return typeof obj; } : function (obj) { return obj && 
typeof Symbol === "function" && obj.constructor === Symbol && 
obj !== Symbol.prototype ? "symbol" : typeof obj; };

which replaces the typeof used in the isObject() and isPlainObject(). It's done to support symbols I assume.
AFAIK we don't need Symbols support in these two methods.

2. The second issue is that the code above is repeated twice, which increases bundle size for no gain.

Is there a way to get rid of that "symbol" support in those functions?

P.S.
Again, this happened again! Bloody ES6, bloody babel, bloody transpiling! I wanna my ES5 days back!
I'm certain that if the code was ES5 from the beginning we won't ever need PR's like that. :)

Babel is obviously over complicated, let's check out Bublé :) #267

[koresar]

It would be great is React-native-packager would behave same as node.js - use the main file from package.json.

I'm liking the Buble approach very much. @Piroro-hs would #267 resolve your issue?

[Piroro-hs]

I've just tried the #267 repo and it works perfectly!(^^)

[koresar]

Great! Closing this one. :)
