Book templates should create a new book

[mira]

Book templates have different logic than other templates. They are not applied to the current book when double clicked. They open a view for their access that is kept in the Library Tab. When the view is closed this access is also closed and next time the user opens the template an exception occurs. Furthermore, the expected behaviour is that the opening book template creates a new book and is applied to this new book.

The problem here is that we keep the accesses to the templates even after they are closed. The solution is simple - we should not open a view to the access kept in the Library Tab but other one.
When an element of the book template palette is double clicked a new book should be created. Its initila model should be the one of the template. This book should be opened in the mainWindow documents.
There is also exception if you try to save a book template with title that already exists. Handle it to notify the user that this name is in use.

The implementation is made according to the design. There is a patch file attached to this ticket.

The previous patch plus more fixes

There is newer implementation patch that takes care of droping of book template on the desktop and save-as-template over an existing one. The new patch is not alteration of the old one - it should be applied on its own.

Merged to the trunk at [8628].

• You should improve the code quality of the classes you update (as FileMenuLogic), but that is only like an advise.
• I fixed some things -> Deyan wanted when you save a book as template to reopen it's book doc window, because the behavior to simply close is strange.

  try {
    fileAccess.save(null);
    ResourceModel model = access.getHead().getModel();
    BookDocView.makeNewBook(model, mainWindow);
    access.close();
				
    mainWindow.documents().get().remove(bookDocView);
    BookTemplateHelper.get().bookTemplates().add(new BookTemplate(fileAccess));
      } catch (IOException e) {
    DialogUtils.showExceptionDialog(bookDocView.swingComponent().get(), e,
      "Couldn't Save Book Template");
    return false;
  }
