Update Unique Keys

In an effort to help make WordPress installations more secure, this plugin will use the WordPress hosted Unique Key generator to update the wp-config.php file with the following keys/salts:

• AUTH_KEY
• SECURE_AUTH_KEY
• LOGGED_IN_KEY
• NONCE_KEY
• AUTH_SALT
• SECURE_AUTH_SALT
• LOGGED_IN_SALT
• NONCE_SALT

If the wp-config.php file is not writable, then the plugin will show the key / salt values on the plugin options page so the admin can then manually update the wp-config.php file.
