This ensures we correctly wait for `component-index.js.tmp` to be written to
disk before trying to rename into place. This fixes an issue where stray temp
files were being strewn about the repos after renaming failures.
This changes the nesting style because some CI / CD systems do not allow moving
to a directory above the checkout for the primary repo (`react-sdk` in this
case).

We've been relying on flow being close enough to TypeScript for so long that it is starting to run into issues. Here we switch to babel's parser given we already use babel in the project.
Babel's parser is also *slightly* faster, allowing us to generate strings 0.1s faster.
Includes: compilation, translations, IDE support (use .tsx not .ts), typings, and other build tools.
TypeScript component have to import PropTypes and React with `import * as React from 'react';`
We were checking out & installing the develop js-sdk explicitly
in cases where we didn't need it at all. We were babeling the src
folder many, many times over (in some cases twice in the same job)
and never using the output at all.
With a switch to Only One Webpack™ we need a way to help developers generate the component index without a concurrent watch task. The best way to do this is to have developers import their components, but how do they do that when we support skins? The answer in this commit is to change skinning.
Skinning now expects to receive your list of overrides instead of the react-sdk+branded components. For Riot this means we send over *only* the Vector components and not Vector+react-sdk.
Components can then be annotated with the `replaceComponent` decorator to have them be skinnable. The decorator must take a string with the dot path of the component because we can't reliably calculate it ourselves, sadly.
The decorator does a call to `getComponent` which is where the important part of the branded components not including the react-sdk is important: if the branded app includes the react-sdk then the decorator gets executed before the skin has finished loading, leading to all kinds of fun errors. This is also why the skinner lazily loads the react-sdk components to avoid importing them too early, breaking the app.
The decorator will end up receiving null for a component because of the getComponent loop mentioned: the require() call is still in progress when the decorator is called, therefore we can't error out. All usages of getComponent() within the app are safe to not need such an error (the return won't be null, and developers shouldn't use getComponent() after this commit anyways).
The AuthPage, being a prominent component, has been converted to demonstrate this working. Changes to riot-web are required to have this work.
The reskindex script has also been altered to reflect these skinning changes - it no longer should set the react-sdk as a parent. The eventual end goal is to get rid of `getComponent()` entirely as it'll be easily replaced by imports.
