This change lets the solver be looked up from the region database, so
that aspects of the solution algorithm can be accessed by
functionObjects and fvModels and similar. For example, a fluid solver
could be looked up as follows:
const solvers::fluid& s =
mesh().lookupObject<solvers::fluid>(solver::typeName);
