-Server Tools: Added new Deployment wp-config.php API setting to bottom of list for checking that the API is enabled.
-Remote Destinations: Added new (enabled) or (disabled) status indicator to Deployment Key button (upper right of page) to quickly see if Deployment is enabled in the wp-config.php.
-Deployment: Fixed issue where API connection could not be completed when running on nginx servers where HTTP header underscores were silently dropped.
