Note: In a previous commit, I began making inc/mod/auth.php more modular with the check_login() function. Including it does NOT check mod login by default anymore like it does on vichan. You have to call check_login(). I've finally included it in inc/functions.php. If you have any custom pages that use inc/mod/auth.php, just including functions.php is enough now.

===================================
Also: backports 351375185e5 (early 404)

This allows pages like create.php to not include inc/mod/pages.php while still being able to use the mod auth functions (like generating salts and passwords)

This reverts commit db3c7f4ee9.

Compatible with earlier versions of PHP. This should work on 5.4 too, but I haven't tested it.
