source-path names are used as filename for target-files

Due to changes on commons.net library the file name which is used to create the target-filename (on local_dir) contains the full path of the source-filename.

This leads into subdirectories in the target_dir and is not intentionally.

if recursion of the source-folder is activated (recurse=yes) then the subfolders within the source-folder are replicated on target-folder.

Enhancement: if this is a feature request it could be implemented by an option, e.g. use_sourcepath_structure=yes
