MDL-32709 Pre-integration trivial clean up

* Added a comment for the BOOK_NUM_* defines.
* Fixed broken redirects in tool/importhtml/index.php
* Fixed typo in book_preload_chapters [subchpaters => subchapters]
* Fixed copy paste docblock error in tool/print/locallib.php
* Removed the .gitignore file as Eloy had previously mentioned that.
