ftp commands are now sent single-write()

                               History of Changes

- Made all FTP commands get sent with the trailing CRLF in one single write()

  as splitting them up seems to confuse at least some firewalls (FW-1 being

  one major).

- Added file desrciptor and FILE handle leak detection to the memdebug system

  and thus I found and removed a file handler leakage in the ftp parts.

- Added an include <stdio.h> in <curl/curl.h> since it uses FILE *.

- Multiple URL downloads with -O was still bugging. Not anymore I think or

  hope, or at least I've tried... :-O
