Export default property in CommonJS and global object

In Babel 5, the ES6 default property was exported as both default
property under the CommonJS export (module.exports) and global object
(in UMD wrapper, on browser). With babel 6 this behaviour was changed
(babel/babel#2212) and now using library
requires e.g.

require("react-modal").default instead of just require("react-modal")
ReactModal.default instead of ReactModal

This babel plugin restores the old behaviour.
