Added the first Partial Gas Pressure: PN2

Browse source 
This makes the beginning of the partial gas pressures, there's
two more. but this code uses a good part of the Model View system,
and it's way clearer than the old one. Luckly the other 2
missing items will be even more clear ( the diffs ) to do,
because I just need to create a new PartialPressureGasItem and
set the properties. <3
