get_magic_quotes_gpc deprecated

[jcoonrod]

Running under php 7.4 generates this warning. Apparently it should simply be removed and not replaced with anything.

When updating from PHP 7.4 to 8.0 it stopped working completely

PHP Fatal error: Uncaught Error: Call to undefined function get_magic_quotes_gpc() in /phpminiadmin.php on line 55

get_magic_quotes_gpc usage removed.

For those who need to use phpminiadmin with older PHP versions - just ensure to turn off magic quotes in your PHP config.
