5.1 releases require ext-ftp

[bytestream]

This is perhaps a docs issue but if you install via composer then it requires ext-ftp, should probably be a suggest if you want to use the FTP component?

Problem 1
    - Installation request for sebastianfeldmann/ftp 0.9.2 -> satisfiable by sebastianfeldmann/ftp[0.9.2].
    - sebastianfeldmann/ftp 0.9.2 requires ext-ftp * -> the requested PHP extension ftp is missing from your system.
  Problem 2
    - sebastianfeldmann/ftp 0.9.2 requires ext-ftp * -> the requested PHP extension ftp is missing from your system.
    - phpbu/phpbu 5.1.9 requires sebastianfeldmann/ftp ~0.9 -> satisfiable by sebastianfeldmann/ftp[0.9.2].
    - Installation request for phpbu/phpbu 5.1.9 -> satisfiable by phpbu/phpbu[5.1.9].

Issue was I installed on a machine with ext-ftp, pushed to git and another machine didn't have ext-ftp.

So if you install on a machine with ext-ftp then it locks sebastianfeldmann/ftp to 0.9.2, and if you install on a machine without then it locks to 0.9.1...

I moved the sebastianfeldmann/ftp package to the suggest list
Now it is not installed by default anymore.
If you want to use the FTP sync, you have to require the lib manually from now on.

Version 5.1.10 is released with the described changes
