created a little command line version

Added new features (FSGetStats, cd with "." or "..")
refactored some parts (file operations now in own operations file)
maybe serveral small bug fixes/improvements I don't remember
limiting read buffer instead of crashing the console

 A port of smea's client (WUPClient.py) for the wupserver.
 
+Open it with
+```
+java -jar jwupclient 192.168.x.x
+```
+
+The following commands are supported (in my ulgy written shell).
+
+cd:
+change directory to parent dir:
+cd .. 
+change directory to relative dir:
+cd code
+change directory to absolute dir:
+cd /vol/storage_mlc01
+
+ls:
+lists content of the directory
+
+dl:
+downloads a file.
+dl filename [targetdir]
+
+dlfp:
+same as dl but keeps the absolute path of the wiiu
+
+dldir:
+downloads a directory
+
+downloading the current dir
+dldir 
+arguments:
+-src <source folder on wiiu> (sets the source folder on the wiiu)
+-dst <destination folder on wiiu> (sets the destination folder on your PC)
+-fullpath (keeps the absolute path of the wiiu)
+
+Server and smea's client.
