Working obview demo

The obview demo is working.

To run the server:

in directory zstar/src-java:
java zstar.server.servermain [udp-port-no] zstar.utils.obview ctlfile obview_controls.ptx modfile cube.ob texfile obview_textures.ptx

The server will be running...

The client zacs must currently be run in the CS (crystal space) directory. To run:

cd CS ; ./zacs [server-host] [server-port] udp

You may need some different options to make zacs work... Crystal space options are appended
to the end. I run with:
./zacs localhost 5000 udp -sdepth=32 -mode=320x200 -video=software

Get a list of CS options with
./zacs localhost 5000 udp -help

I will build in a help invoke in the future that doesn't requre a host name, etc.
