Summary:
This replaces ActivityIndicatorIOS and indeterminate ProgressBar that were deprecated recently with ActivityIndicator across the codebase and examples and a few other cleanups.
This also make a small tweak to ActivityIndicator so it uses the Android theme color instead of gray when no color is specified.
Use Slider instead of SliderIOS in CameraRoll example.
Remove the line about unifying ActivityIndicator and ProgressBar.
**Test plan**
Tested the affected components in UIExplorer on iOS and Android, tested the changes made in Movies example on iOS and Android.

Summary:First I searched for special cases that destructor PropTypes:
```
(?s)React\s*=\s*require\('react\-native'\).*(Children|PropTypes)[^\{\}]*\}\s*=\s*React;
```
I split them up manually.
Then I replaced the React = require('react-native') + destructuring pattern...
```
(?s)(const|var)\s+React\s*=\s*require\('react\-native'\)(.*[^\{\}]*\}\s*=\s*)React;
```
...with...
```
$1 React = require('react');
$1 ReactNative = require('react-native')$2ReactNative;
```
I used lint to figure out if I left some unnecessary imports.
Finally I grepped for just
```
React\s*=\s*require\('react\-native'\)
```
to catch any remaining patterns.
Also, `} = React.NativeModules` -> `} = ReactNative.NativeModules`.

This is an early release and there are several things that are known
not to work if you're porting your iOS app to Android.
See the Known Issues guide on the website.
We will work with the community to reach platform parity with iOS.
