Support generating a UMD bundle

Choose one: feature request?

Right now, parcel is used for compiling code to be used for a frontend server. There’s no way to create a named library that you can use drop in a <script src='...'> tag and call via myLibrary.Foo(). Both rollup and webpack allow you to specify a config similar to

output: {
    file: 'dist/styled-components.js',
    format: 'umd',
    name: 'styled',
    exports: 'named',
}

It would be awesome if parcel supported something similar and wasn’t strictly for server/html code.

Fixed by #453. Modules are now exposed to CommonJS and AMD automatically, and if you specify a --global <name> flag, as a global variable.

@niieani - I’m not sure why this is not in V2, but here is my workaround:

window['MyGlobalName'] = myGlobalVar;

Need umd/iife format in v2 it is expected to bundle all dependencies into the final bundle expect the native node modules. I guess your workaround won’t handle the dependencies bundling problem.
