* MonoDevelop.Ide.Gui.Pads/NodeCommandHandler.cs,

  MonoDevelop.Ide.Gui/MonoDevelopTreeView.cs: Handle delete commands
  in the base node command handler instead of the tree view, so that
  subclassed command handlers can override them properly.
* MonoDevelop.Ide.Gui.Pads.ProjectPad/ProjectFileNodeBuilder.cs: Don't
  allow deleting child files. Fix bad casting pattern. 
* MonoDevelop.Ide.Tasks/TaskService.cs: Avoid an exception on closing
  solutions without user tasks.
