Changed the button index back to the way it was before.  Even though there are only 7 buttons on each device, the buttons on the right-hand control are indexed starting at 8.  This is wasting part of our name space, but will avoid client applications having to change their code.  This is now documented in the vrpn.cfg file so that people will know not to look for button 7.  Removed optional 'recalibrate' button from vrpn.cfg, since it is no longer needed (or available).

Added code to support a SpaceMouseWireless based on info provided by Mathieu Ruffat.  Also added a check to see if we're getting packets of unusual size, which may explain why this device's reports are not being handled properly.
Handles all incoming reports when update() is called, not just the first one it find.  This keeps latency from accumulating for devices that send lots of reports.
Changing vendor ID for Space Mouse Wireless per info from Mathieu Ruffat.
