TekSavvy → SB6120 / SB6121 Logger Update

As always:
If your log is getting too big, delete from the BOTTOM UP. Do not delete above line 9 or you'll break it.

Major bug fixes:
- Updated so it always charts most recent stats
- Fixed Error Rate % so it actually displays correct numbers if Upstream has both 16QAM & 64QAM (which should be most areas now)

Added:
- Added Error Rate % chart

Note:
With a bit of modifying, you can get it working with the SB5100 series, as well as with Office for Mac.

Note 2: The downward spikes showing on the "SB6120 Downstream SNR" are modem restarts due to modem sync issues. This is bad (also my connection right now due to botched Rogers install). Your connection shouldn't look like this.

Oh hey great, thanks for the update I betcha worked hard on that in between modem reboots appreciated

Thanks resa. Just wish my Sb6120 hadn't died on me and I could use this. I'm using a DCM475 now.

Few minor changes which make it work better.
