audioChat
---------

Added audio chat tool. The tool is based on CAVERNsoft and runs
seperately from CAVE QUAKE II. Part of the reason is that I'm
concerned about audio feedback. You may need to use a headset
microphone.

To run between two machines "foo" and "slop", type "runChat" on foo
and "runChat foo" on slop. Make sure that both your input and output
sample rates are the same as your vss2.2 server (usually 32kHz).

Thanks to Jason Leigh and Nikita Sawant for this tool!
