Added well constraint checking to SimulatorIncompTwophase.

- Changed Wells constructor arg for SimulatorIncompTwophase to WellsManager.
 - Insert checking code for well constrains (mostly copied from spu_2p.cpp).
Unrelated to the above changes.
 - Added pressure normalization for incompressible case (from spu_2p.cpp)
