Changes

I also added #default_form lines at the end of the Book and Author template pages, e.g. for the Author template page, the last few lines looked like:

...

[[Category:Authors]]

{{#default_form:Author}}

</includeonly>

and I did something similar for the Book template page. This way, every Book and Author page will have a "Edit with form" tab in addition to the "Edit" tab (and the "edit with form" tab is significantly more useful).
