VIVO-873 Adapt the client code to the new interface.

Create a bridge implementation of SearchIndexerImpl that just wraps around an old IndexBuilder.

Modify client code:
Application, BasicAuthenticator, SearchServiceController, SparqlUpdateApiController,
UpdateUrisInIndex and VClassGroupCache

Rewrite IndexController to use AJAX and to show the current status and history of the indexer events.
