DavisLogger: log absolute pressure as well as MSL #150

Currently Davis archive records only include Mean Sea Level Pressure. The 2.5 second Loop2 packets to include absolute pressure though so we could calculate the 5 minute average for that ourselves.

The big problem really is we can only compute this value while davis-logger is running. If its stopped for any period then the AbsolutePressure column would have to be null for the length of time it was stopped. Not ideal but at the moment the column is always null so occasional data is no worse than the current situation.

If this is done we may want to consider surfacing absolute pressure in the desktop app in addition to MSL pressure.
