Set ImageGetter in compartment mappings once, allowing MEF extension to add customized images. EFModelDiagram.cs: Record the mousedown location to allow placement of new shapes in diagram. CommandSet.cs: Add new Solution Explorer menu with 'Generate Code'. Add new 'Add Entity' context menu item to diagram menu. Added Icons for both. LayoutCommand.cs: make LayoutDiagram methods public so MEF extensions can call them. Commands.vsct: Added Solution Explorer manu and cleanup. DslPackage.csproj: Added new files.
