[horde] Install disaster

[Andy Theuninck]

OK, so I kind of see the problem. It's redirecting in a loop.

After setting up frames, login.php redirects to index.php (because
Auth::isAuthenticated() returns true). In turn, index.php tries to
find the selected URL (with Util::getFormData('url')), comes up empty,
and redirects back to login.php.

What *should* be happening here?

test.php comes back fairly clean (no on mime_magic but yes on
fileinfo, no on Services_Weather, Cache, and XML_Serializer).
