ensure the internal PHP scripts work even if system-wide PHP settings are set that could affect how ISPConfig would work. See FS#3293

- Changed apache_ispconfig_fcgi_starter.master: PHP environment variables must be set before PHP is executed.

- ISPConfig's fcgi_starter script had two PHP_FCGI_MAX_REQUESTS variables; I removed one of them. In addition to that I added "-d magic_quotes_gpc=off" to the PHP executable to turn off magic_quotes_gpc.
