Double IDs in login form (because in header and userbar)

[halk]

The form elements user_login, user_pass, rememberme and wp-submit define the equal ID attributes.

But when you have the login form in the header and in the userbar you have these IDs twice. This is not XHTML compliant and triggers warnings.

[r-a-y]

Removing the ID for the hidden fields should validate the XHTML and leave the form elements working.

What do the devs think?

Sounds like a good solution, we'll fix this for 1.1.
