Disable autocomplete on user_edit form

When using a mobile browser (Android 2.2 stock):

• Log in with your usename
• When the browser asks, save the password
• Go to user/edit

Now the browser autocompletes the form with your current password and username (which is usually wrong).

A simple solution is $form['#attributes'] = array('autocomplete' => 'off');.
This won't hurt any other functionality, but on this form it can save you headaches.

I suggest using this on other forms where it might cause problems also.
