Subject: [PATCH] Fixing some issues where the atmos sensor was too sensitive.
 Only change is with CO2 at this point, may or may not adjust that in the
 future.

Resolved what appears to be an old bug with the CO2 detection system causing alerts for CO2 at 0.05kPa and 0.1kPa when the minimum value to cause harm is 10kPa. Updated values to 5 and 10 kPa for minor/severe alerts respectively.

Also introduced detection for "unknown gases", which basically consists of N2O.
