[Java-player-developers] patch for PlayerClient.close()

[Kurt K. <kon...@AI...>]

This function hangs when talking to Stage (haven't tried it with a real 
robot).  It's waiting for a response to a device close request, which 
Stage never sends.  Took out the close request, just shut down the I/O, 
which closes the Stage connection.  Also added setNotThreaded code to 
wait for thread to exit.

Patch is against the latest SVN.

Cheers --Kurt
