VigorStats 4.1

Version 4.1 Release notes
--------------------------
Logfile now called vigorstats.csv
Quit button added
Extra 5 fields (FcDeltaCRC, FcDeltaHEC etc) added at start of log, showing changes/delta error rates (derrived from the other fields). Not sure all these fields are populated by the vigor.
Only Fast Channel delta errors, not Interleaved.
Default sample period changed from 5 minutes to 1 minute
Latest data collection time displayed correctly
Please note error handling is not very robust in this version. If you telnet in to you router, or open the CSV file while vigorstats is running it is probable it will stop recording. This will be fixed in a future release.
