Summary:
Initial conversion of RNTester to support light and dark themes. Theming is implemented by providing the desired color theme via context. Example:
```
const ThemedContainer = props => (
<RNTesterThemeContext.Consumer>
{theme => {
return (
<View
style={{
paddingHorizontal: 8,
paddingVertical: 16,
backgroundColor: theme.SystemBackgroundColor,
}}>
{props.children}
</View>
);
}}
</RNTesterThemeContext.Consumer>
);
```
As RNTester's design follows the base iOS system appearance, I've chosen light and dark themes based on the actual iOS 13 semantic colors. The themes are RNTester-specific, however, and we'd expect individual apps to build their own color palettes.
## Examples
The new Appearance Examples screen demonstrates how context can be used to force a theme. It also displays the list of colors in each RNTester theme.

https://pxl.cl/HmB3 (screenshot: Same screen, with light and dark RNTester themes visible)
Theming support in this diff mostly focused on the main screen and the Dark Mode examples screen. This required updating the components used by most of the examples, as you can see in this Image example:
https://pxl.cl/H0Hv (screenshot: Image Examples screen in Dark Mode theme)
Note that I have yet to go through every single example screen to update it. There's individual cases, such as the FlatList example screen, that are not fully converted to use a dark theme when appropriate. This can be taken care later as it's non-blocking.
