[Trinidad2] InternalView VDL/TRINIDAD-1735

[Max Starets]

Hello Everyone, While I was working on a solution for TRINIDAD-1735, I realized that the clean solution would involve moving all the code dealing with InternalViews from the ViewHandlerImpl to the new ViewDeclarationLanguageFactoryImpl.  We also would expose a special VDL for the internal views, which is what Martin Koci suggested a while ago. Pleas review the jira and the associated patch. If there are no objections, I will commit the change in a few days. Thanks, Max
