#1 Fix notice messages

[Ole Thomsen Buus]

Index.php running on IIS 6 on Windows Server 2003, PHP 5.x emits a bunch notice messages due to use of undefined variables:

Notice: Undefined index: folder in /index.php on line 45

Notice: Undefined variable: _temp in /index.php on line 142

Notice: Undefined variable: total_size in /dirLIST_files/functions.php on line 41

Notice: Undefined variable: total_size in /dirLIST_files/functions.php on line 37

Notice: Undefined variable: total_size in /dirLIST_files/functions.php on line 33

Note that Notice messages are enabled by default on Windows builds of PHP.

This has not effect on actual script functionality.
