Title: Allow for web server-based authentication that sets REMOTE_USER

Some web servers provide external authentication mechanisms that
simply set REMOTE_USER. Allow for the use of those. Globally, if
$GLOBALS['OUTSIDE_USER'] is set, we assume that either
ALLOW_HTTP_AUTH or ALLOW_REMOTE_USER is set, and that OUTSIDE_USER
contains the username.
