Progress Report 04/02

• Motes now read their configuration information (user ID and device ID) from flash memory when they are booted up.
• Added a "GetConfig" message and response that can be sent over the serial port, so that a PC can get the current configuration of the device attached to it.
• Maybe the motes do receive packets in little endian format - when I started using the GetConfig message the device/user IDs were coming out backwards. I guess data is stored in the flash little endian (and displayed like this in FlashViewer), but is actually retrieved big-endian.
