Updates to RAP 2.2.0

There were two breaking changes from the previous version that was
fixed with this commit.

1. WidgetDataWhiteList is no longer a ClientService. Tabris
   now registers the Data keys itself in the TabrisClient
   initialization.

2. IClientObject has finally been removed. The VideoLifeCycleAdapter
   is updated to use the RemoteObject API.
