BUG: pay to blog may be unupdateable

Hej,

On pay to blog module line: 72
the function says:

function settings_process($settings) {
	  $settings['ptb_front_disable'] = isset($settings['ptb_front_disable']) ? 1 : 0;
	  return $settings;
	}

But, if someone is using the psts_settings_filter before this function it will always return 1.

Therefor it should be:

function settings_process($settings) {
	  $settings['ptb_front_disable'] = isset($settings['ptb_front_disable']) ? $settings['ptb_front_disable'] : 0;
	  return $settings;
	}

Thanks,

Koff
