Summary:
Our docs suggest using this babel plugin to remove console.log statements in production. Unfortunately, it does not actually work when you run it on a new React Native project, and the root cause is that the plugin does not handle all cases correctly. See discussion in https://github.com/facebook/react-native/issues/10412 . For now, we should just stop recommending that people use this plugin, because it doesn't work.

Summary:
Adding documentation for the CLI for 2 reasons:
1. It's not immediately clear to most how the CLI is part of `react-native` and not the node module they installed. This begins clarifying.
2. I plan on adding some additional documentation to this section pending an upcoming PR I've discussed with Mike.

Summary:
As said in #10944, there's not yet some good infos on how to profile the javascript.
I'm adding a mention to two ways of doing it (`react-addons-perf` and chrome profiler), feel free to correct me on this.
I almost added an example for `react-addons-perf` but I'm not sure what's the correct way to use. Here's the way I use it:
```javascript
import Perf from 'react-addons-perf';
....
componentDidMount() {
console.log('start perf tracking');
Perf.start();
setTimeout(() => {
console.log('stop perf tracking');
Perf.stop();
Perf.printExclusive();
}, 10000);
}
...
```

Summary:
P.S, now we have four docs about navigator(s). But from my POV, the content are more or less repeated, and the logic is a little messy. I suggest someone to reforge these docs, in a more vivid and evolutionary way. Thank you!

Summary:
We had rendering support for prev links, but we never had any previous links in our metadata. Only next links. This adds that support to both Guides and APIs.
**For guides**: `previous` is manually inserted into the metadata of the actual markdown file.
**For APIs/Components**: `previous` is established via code within `extractDocs.js`
> This isn't totally perfect. For example, the transition from the last guide to the first API/component has a next link from the guide, but not a previous link from the API since the way you get the previous links are different from guides and APIs. But this gets us really close.
