Tor Harald Sandve 3c5b0b9e73 Add interface for wet gas 
The pvt interface is extened to handle wet gas
1. A function for rvSat is added to the interface
2. An interface that takes rv and the fluid condition as an input for
the gas properties is added. The old interface without rv and the fluid
condition is kept in the file.
3. The new interface is implemented in BlackoilPropsAd and
BlackoilPropsAdFromDeck.

A simulator that tests wet gas is not yet implemented.
