Title: Allow update of solver parameters.

It's handy to be able to update the solver parameters after it has been instantiated. The Dolfin solver interface allows this, so it is also a good idea from the perspective of remaining as compatible as possible.

The `KspSolver` class required all the supported parameters to be passed, and there would be a KeyError if there were any missing. Now, parameter setting only attempts to set those parameters that have been specified.
