Change autocomplete value to new-password

This was a breaking change in Chrome M34 that has been fixed in M37: The password manager would completely ignore the autocomplete="off" directive and would still fill up the first input[type=password] it could find.

This was making me nervous since I spotted my password getting saved in plain text in the config file.

The only was to fix (without any hacks) is to use the new value "new-password" (See https://code.google.com/p/chromium/issues/detail?id=370363#c8 and http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2014-March/253895.html)

I've only changed the password field and left the username field untouched.

I've tested it in Chrome and Firefox (both do well).

This would need testing in Safari.
