Bug description

When you set Frontpage in the admin area to login.php, the site ends in too many redirections.

In index,php is $inc set to login.php
then this file is included include($inc);
e_SELF is "" {if you don't use index.php)
e_LOGIN is login.php
then this test is true: e_LOGIN != e_SELF in login.php and this code is executed:

$prev = e107::getRedirect()->getPreviousUrl();
	if(!empty($prev))
	{
		e107::redirect($prev);
		exit();
	}
	e107::redirect();
	exit();

the previous URL is the homepage and this homepage again redirects to login.php
and site loading fails
