#120 $PHP_SELF - change to $_SERVER['PHP_SELF']

[Anonymous]

In adminpear/inc/showform.php:

it would be better to use $_SERVER['PHP_SELF'] instead
of $PHP_SELF.

See:
http://us4.php.net/reserved.variables

Anyway a lot of the admin screen is being rewritten as
a class, so this fix will be in the new class(es).
