Resume and constitent sending files and directories are buggy

[GentleRV]

Filezilla was working for about 4 days when I started to notice that the same files were send over and over.
Watching is closer I see that a connection error appear, the resume counter was not updated and the file started to upload from a much earlier position.
Later I see that this was a kind of loop as the connection error was always generated after a certain amount transferred data which was different for each file.
After restart filezilla I noticed that all the transferable files where still in the list but the succes fully and non transferable file list were empty.
