Fix typo in manual
Add reordering of second order derivatives to stochastic_solvers.m

It was erroneously completely moved to dyn_second_order_solver.m in the 4.3 branch when cleaning up dr1.m. Without this reordering, decision rules for exogenous deterministic variables at second order are wrong
Add unit test for correctness of forecasting with exogenous variables
