Add choice of solution strategies to simulators.

Browse Source 
The following is changed in this commit:
 - The constructor for NewtonIterationBlackoilSimple now takes
   a parameter object instead of a linear solver.
 - The fully implicit black-oil simulators can now use the CPR
   preconditioning strategy (by passing use_cpr=true) or the
   simple strategy (the default).
Note that as of this commit, the CPR preconditioning still has
not been implemented properly, and behaves just like the simple
strategy.
