also prevent change username, prevent change user 1

I wanted to restrict some things in addition to password changes:

1- block username changes (if password and e-mail are restricted, changing username could still cause problems)

2- prevent blocking changes to admin user 1

I added some code to this module to do the above.

Here is the result, which seems to work:

(all this code is in the file restrict_password_change.module, after (about) line 27, inside the IF clause that blocks password changes)

// username cannot be changed
$form['account']['name']['#access'] = FALSE;

// prevent changing admin user
if ($form['_account']['#value']->uid == 1) {
$form['account']['#access'] = FALSE;
$form['theme_select']['#access'] = FALSE;
$form['contact']['#access'] = FALSE;
$form['submit']['#access'] = FALSE;
$form['timezone']['#access'] = FALSE;
$form['messaging']['#access'] = FALSE;
$form['delete']['#access'] = FALSE;
// block admin changes ONLY for other users - not for admin!
} // if user 1
