* [Example] Get tests passing on ReduxExample and NavigationPlayground
* [CI] Use more vague versioning so we're always up to date
* [CI] Test that the example apps run without error
* [CI] Install the current local version of react-nav before testing
* Fix tabs => spaces in ReduxExample/package.json
* Remove LinkingExample entirely
It's now part of NavigationPlayground.
* [Example] Upgrade dependencies to fix the ReduxExample app
* [Example] Also upgrade and fix the LinkingExample app
* [Example] Update MainApplication.java to fix Android API
* [Example] Fix the ReduxExample app
Just a bit of cleanup so it can run.
* [Example] Remove AsyncStorage persistence from ReduxExample
It's a cool feature, but isn't necessary to demonstrate how to use
react-navigation and may cause more confusion than it's worth.
