Check if FTP extension is loaded if ftp is used

[ghost]

I got this error:

 Notice: Use of undefined constant FTP_BINARY - assumed 'FTP_BINARY' 

Issue was that the php extension ftp.so was not loaded. I use PHP 7.0.13. I think this bundle should include a check to only allow usage of the ftp feature if the "ftp.so" extension is loaded - otherwise it should throw a better understanding error message.

Also an issue for me because we don't use an FTP connection, we don't include the FTP extension

Issue for me too.

An issue for anybody with PHP7 that didn't explicitly load the FTP module.
