RoboRio Losing WPILib Preferences

[kylelanman]

I didn't realize this thread picked back up....As we were doing additional testing we ran into instances where calling save was not actually saving the file. We verified this with 'watch -n1 cat filename' in an ssh session. At that point we ripped out Preferences and used our own implementation from last year because we knew it was reliable. I will try to submit a bug report in the next couple of days with the details.
