themes/default/login.php: fix stray closing tag
themes/default/login.php: fix stray closing tag

Main container gets closed in parts/_footer, so we need to leave it open.

That makes login.php identical to index.php.
Rather than wrangling with the indentation for this pecularity myself,
I just copied index.php verbatim.  So for now, at least they're consistent.
