Major bug in FTPSync 1.3.07

Unfortunately an OpenSource nightmare scenario has hit FTPSync with 1.3.07: It uploads files even in download mode.

I have fixed the bug #38906 with git commit 65c0a4fed73b719352e5fa00096a4081d9cc3a63, but I actually recommend to use the re-released ftpsync-1.3.06-0.tar.bz2.
