failed on /sim/time/gmt-string because the raw value contains an embedded
space. Now I use a regex instead of a plain split(). I also removed the
view_next and view_prev functions. These will have to be replaced with

I've also added a FGFSDemo.py script which is a python version of David's java program.
simplistic, text-field oriented interface for major property groups.
The JAR is now executable, so the program can be launched with
java -jar fgfsclient.jar <host> <port>
