* Added initial documentation for the browser-session component: https://github.com/mozilla-mobile/android-components/blob/master/components/browser/session/README.md
* **sync-logins**: New component for integrating with Firefox Sync (for Logins). A sample app showcasing this new functionality can be found at: https://github.com/mozilla-mobile/android-components/tree/master/samples/sync-logins
* **browser-engine-***:
  * Added support for fullscreen mode and the ability to exit it programmatically if needed.
  ```Kotlin
  session.register(object : Session.Observer {
      fun onFullScreenChange(enabled: Boolean) {
          if (enabled) {
              // ..
              sessionManager.getEngineSession().exitFullScreenMode()
          }
      }
  })
  ```
* **concept-engine**, **browser-engine-system**, **browser-engine-gecko(-beta/nightly)**:
  * We've extended support for intercepting requests to also include intercepting of errors
  ```Kotlin
  val interceptor = object : RequestInterceptor {
    override fun onErrorRequest(
      session: EngineSession, 
      errorCode: Int, 
      uri: String?
    ) {
      engineSession.loadData("<html><body>Couldn't load $uri!</body></html>")
    }
  }
  // GeckoEngine (beta/nightly) and SystemEngine support request interceptors.
  GeckoEngine(runtime, DefaultSettings(requestInterceptor = interceptor))
  ```
* **browser-engine-system**:
    * Added functionality to clear all browsing data
    ```Kotlin
    sessionManager.getEngineSession().clearData()
    ``` 
    * `onNavigationStateChange` is now called earlier (when the title of a web page is available) to allow for faster toolbar updates.
* **feature-session**: Added support for processing `ACTION_SEND` intents (`ACTION_VIEW` was already supported)
   
  ```Kotlin
  // Triggering a search if the provided EXTRA_TEXT is not a URL
  val searchHandler: TextSearchHandler = { searchTerm, session ->
       searchUseCases.defaultSearch.invoke(searchTerm, session)
  }
      
  // Handles both ACTION_VIEW and ACTION_SEND intents
  val intentProcessor = SessionIntentProcessor(
      sessionUseCases, sessionManager, textSearchHandler = searchHandler
  )    
  intentProcessor.process(intent)
  ```
* Replaced some miscellaneous uses of Java 8 `forEach` with Kotlin's for consistency and backward-compatibility.
* Various bug fixes (see [Commits](https://github.com/mozilla-mobile/android-components/compare/v0.22...v0.23) for details).
