Duplicate file names.

Be careful when downloading files for chapter 10. Some of
these files have the same name as files used in previous
chapters. You could accidentally overwrite those files you
worked on in previous chapters.
Here are just some of the files that may be affected


public_files/css/calendar.css - It is different
public_files/css/styles.css - It is different

public_files/js/ajax.js - appears to be the same

public_files/img/captacha.php - It is different

public_files/401.php - for me this was different than the previous one
public_files/login.php - this appears to have changed from the original login.php
public_files/view.php - This file is in chapter 2 and chapter 7.
I renamed mine view10.php
public_files/admin.php - This file is in chapter 4. I renamed mine admin10.php.
