Fixes

• When a requesting IP address cannot be found, default to 127.0.0.1. This fixes issues with some alternate cron setups.
• Having more than one iThemes Security modification in a .htaccess, nginx.conf, or wp-config.php file will no longer result in having all the file content between each section removed when updating the file.
• Modifications to the wp-config.php file added by W3 Total Cache now have their Windows-style newlines preserved when iThemes Security updates the file.
